Match the Cable Route and Screw-Locking Interface
Locking Micro USB Cable
A loose USB connection can interrupt a useful piece of equipment even when the cable route looks tidy. The BC-DAD007 locking Micro USB series combines USB-A-to-wide-Micro-B connectivity with screw-retained connector options for equipment that provides the matching mechanical interface. Eighteen listed configurations let you select cable direction and retention separately at the host and device.
The screw arrangement must match the equipment. A single-screw connector isn’t interchangeable with every dual-screw housing, and adding retention doesn’t provide a vibration rating, medical approval, or a data-rate guarantee. Start with the mating drawing and choose the model around the actual installation.

Match the Socket and Retention Pattern
The wide Micro-B plug requires the corresponding USB 3.0 Micro-B receptacle. It will not fit a narrow five-pin Micro-B socket. Confirm the mating thread position and the electrical connector. Do not use the screws to pull a misaligned plug into place or apply a tightening value that has not been specified for the assembly.
Choose Length with Data and Power in Mind
A short sample and a long production cable are not equivalent electrical tests. Longer runs increase resistance and can reduce signal margin. Confirm device recognition, the required data function, and startup load with the chosen length. The 5Gbps designation is a signaling rate, not a guaranteed file-copy speed.
If your equipment has mounting holes but a different fastening arrangement, compare the Micro-B mounting-hole cable. For a connection without matching threads, review the non-locking options in the Micro USB cable range.
Straight USB-A with Five Micro-B Exit Options
Choose straight, down, up, left, or right Micro-B routing. Lengths for this group are 0.3m, 1m, 1.8m, 3m, and 5m. Confirm availability and electrical performance for the selected model and length; the list does not guarantee 5Gbps at every distance.
P/N: BC-DAD007-SSD
The straight USB-A and straight dual-screw Micro-B arrangement is the starting point when both ports have rear clearance. Match the Micro-B retention pattern to the device and choose the required length after checking the complete cable route.
P/N: BC-DAD007-SDD
A straight USB-A end pairs with a downward-angled dual-screw Micro-B connector. Use this version when the device-side route needs the downward exit shown in the model drawing, while leaving room for screw access and strain relief.
P/N: BC-DAD007-SUD
This version turns the dual-screw Micro-B exit upward while keeping the USB-A end straight. Before approving the route or selecting a production length, check the installed port orientation, overhead clearance, and access to the retention hardware.
P/N: BC-DAD007-SLS
Choose the left-angle single-screw Micro-B option when the device offers the corresponding retention point and side clearance. The USB-A connector remains straight. Confirm the screw location and viewing direction rather than selecting by the left-angle name alone.
P/N: BC-DAD007-SRS
The right-angle single-screw Micro-B connector offers an alternative device-side exit with a straight USB-A host connection. Verify the mating thread position and adjacent-port clearance, then assess the selected length with the actual device and power source.
Angled USB-A with Straight Dual-Screw Micro-B
Change the host-side exit while retaining a straight dual-screw Micro-B connector. Available lengths are 0.3 m, 1.8 m, 3 m, and 5 m; confirm the chosen length with the host, device, and power requirements.
P/N: BC-DAD007-DSD
The down-angle USB-A plug changes the host-side routing, while the Micro-B connector remains straight with dual-screw retention. Check the host orientation and leave enough space behind the device for its housing, fasteners, and cable transition.
P/N: BC-DAD007-USD
An up-angle USB-A end is paired with a straight dual-screw Micro-B connector. This configuration addresses host-side clearance without changing the device-side exit. Confirm both installed views and the mating retention pattern before selecting the assembly length.
P/N: BC-DAD007-LSD
Use the left-angle USB-A variant where it matches the available host-side route. The device end uses a straight dual-screw Micro-B connector, so the layout still needs to include rear clearance and access to both fasteners.
P/N: BC-DAD007-RSD
The right-angle USB-A connector provides another host-side routing choice with straight dual-screw Micro-B retention. Compare the host port orientation to the drawing, and ensure the final route does not twist or pull on the device connector.
Two Angled Ends with Single-Screw Micro-B
LRS, LLS, RLS, and RRS combine left/right exits at both ends with a single-screw Micro-B connector. The listed standard length is 0.3m. Check both viewing directions and the device retention point.
P/N: BC-DAD007-LRS
A left-angle USB-A end and right-angle single-screw Micro-B end create this two-ended routing option. Confirm each direction using the installed port views; the short-listed assembly must reach both sockets without twisting, and the device retention point must match.
P/N: BC-DAD007-LLS
Left-angle connectors at both ends use single-screw retention at Micro-B. Check the host and device mounting positions before assuming the route is parallel. Allow access to the locking screw and enough cable freedom for installation and service.
P/N: BC-DAD007-RLS
This model pairs right-angle USB-A routing with a left-angle single-screw Micro-B connector. Use it when the opposite device exit is obstructed. Use a two-end sketch to verify housing clearance, cable direction, and the required retention interface.
P/N: BC-DAD007-RRS
Right-angle USB-A and right-angle single-screw Micro-B connectors provide this combination. The final route depends on how the equipment ports face, so confirm both views and the mating screw position before approving the short cable assembly.
Down/Up Routing with Dual-Screw Micro-B
DDD and DUD use a down-angle USB-A end with a down- or up-angle dual-screw Micro-B connector. The listed standard length is 0.3m. Confirm access to the fasteners and the route between the housings.
P/N: BC-DAD007-DDD
Down-angle connectors at the host and device ends use dual-screw Micro-B retention. Check the two port orientations, the space needed for each housing, and the route between them; identical angle names do not establish installation fit.
P/N: BC-DAD007-DUD
The down-angle USB-A and up-angle dual-screw Micro-B combination changes the device’s exit plane. Compare both ends with the installed equipment and confirm fastener access before choosing this version for a compact, short cable route.
Screw Retention at Both USB-A and Micro-B
These models add dual-screw retention at the straight USB-A end. Choose straight dual-screw, right-angle single-screw, or left-angle single-screw Micro-B. Listed lengths are 0.3 m, 1 m, 2 m, and 3 m; verify the selected complete connection.
P/N: BC-DAD007-SDSD
This version uses dual-screw retention on both straight USB-A and straight Micro-B connectors. Match the hardware interface at each device, including thread engagement and housing clearance. Retention at both ends still requires cable support and verification of the selected length.
P/N: BC-DAD007-SDRS
The straight dual-screw USB-A connector pairs with a right-angle single-screw Micro-B end. Confirm both retention patterns and the device-side exit on the drawing; do not treat the different screw arrangements as interchangeable with another model.
P/N: BC-DAD007-SDLS
This model combines a straight dual-screw USB-A end with a left-angle single-screw Micro-B connector. Choose it when the left device-side exit matches your layout, and verify the exact model against the image and mating threads before approving the sample.
Confirm the Retention Pattern Before Ordering
Locking starts with a matching connector and retention pattern. This series offers both single- and dual-screw Micro-B arrangements, with selected models also retaining the USB-A connection.
Use the model photograph to identify the layout, then check the exact thread, spacing, engagement, and housing dimensions on the mating drawing. Seat the connector correctly before securing it, and support the cable so the locking hardware doesn’t carry an uncontrolled external load.
The variants address different port orientations and retention patterns. Start with the mating connector and screw arrangement, then choose the host and device exits. Eighteen options do not imply that every model fits every piece of equipment.
A compatible USB 2.0 host may operate through the USB-A end at its supported rate. The wide USB 3.0 Micro-B plug still requires a matching receptacle and cannot fit into a narrow five-pin Micro-B socket. Mechanical retention must also match separately.
Confirm the thread, spacing, engagement length, and tightening instructions on the model-specific drawing and the equipment interface. Do not assume one M2 or M3 specification applies to every single- and dual-screw variant.
Send a drawing showing both port views, the desired exits, and retention points. We can review alternative configurations for tooling and electrical feasibility. Minimum quantity and sample requirements are confirmed in the quotation.
The series supports USB signaling up to 5 Gbps. Confirm performance for the selected length and complete connection, especially for longer assemblies. Actual file-transfer speed depends on the host, device, and workload.
A medical application requires its own system assessment, qualification, and documentation. The connector shape and locking feature do not establish medical suitability. Provide the applicable requirements so we can review the exact cable construction.
The passive cable does not require its own software driver. Operating-system compatibility depends on the connected device, controller, and their drivers. Check those components rather than treating a cable OS list as a guarantee.
Data communication and bus power can operate together when the connected equipment supports them. Available current depends on the source, device, and cable construction. Screw retention does not add USB-C Power Delivery or automatically enable fast charging.
Provide the model, length, and required quantity for a specific quotation. The minimum quantity depends on materials, customization, and production setup; don’t assume a single value applies to every configuration.
Share the quantity, required delivery date, destination, and any sample-approval steps. We confirm the lead time based on the agreed specification and material availability. Custom tooling or validation may affect the schedule.
Send the complete part number or a two-end sketch, mating thread and spacing details, length, quantity, device load, and required documents. These inputs will let us review the electrical connection and retention method together before providing a quotation.
Qualifying a Screw-Locking Micro-B Connection for Equipment
A locking cable helps only when you consider mechanical and electrical requirements together. The screw feature can retain a properly mated connector, but it can’t fix an unsuitable port, an inadequate power source, or an unverified long cable run.
Identify Where Retention Is Needed
Decide whether the device end alone needs retention or whether both the host and device require it. The BC-DAD007 range separates ordinary USB-A ends from dual-screw USB-A versions, and straight dual-screw Micro-B ends from angled single-screw variants. Select the appropriate arrangement rather than assuming more screws automatically mean a better fit.
Request a Model-Specific Mechanical Drawing
Confirm thread designation, center spacing, engagement length, housing envelope, and tool access at each retained end. Identify any panel or fixture that carries the load. Compare the drawing with the equipment, not only with another cable photo. Single- and dual-screw patterns require different mating provisions.
Approve the Cable Exit in the Installed Position
Mark both port views and the desired route. Left, right, up, and down are only useful when the viewing reference is shared. Allow a gentle transition after the strain relief and room to disconnect the cable for service. Do not twist a short assembly to compensate for the wrong angle combination.
Validate the Selected Length
The family includes longer listed lengths, but listing a length does not prove identical signal performance across the range. Test the actual length with the intended host, device, and any intervening equipment. Confirm enumeration and the required data operation, and include startup or active-load conditions for bus-powered devices.
A storage benchmark measures the whole system. Keep the equipment and workload consistent when comparing samples, and distinguish negotiated USB link speed from file-copy throughput. Likewise, a cable does not automatically deliver charging current just because its description mentions a charging standard.
Define Any Environmental Qualification Separately
If the application requires vibration, pull-load, flex-life, or temperature testing, specify the method, fixture, and acceptance criteria. A screw-retained connector does not prove compliance with a military test method or a medical-device requirement. Confirm the applicable documentation for the exact assembly before making those claims in your own product.
Build a Repeatable Purchasing Specification
Record the complete BC-DAD007 part number, length, mating drawing, conductor and shielding requirements, labeling, and packaging. Include the required sample checks and production acceptance records. A clear specification reduces reliance on interpreting connector names or product photographs for reorders.
For a configuration review, send the two-port photos and mating drawings with quantity, device power demand, and delivery requirements. If the equipment uses mounting holes instead of a matching screw-lock pattern, compare the mounting-hole Micro-B cable before finalizing the design.
