Locking USB-C cable for docks

This 50cm USB-C to USB-C cable uses a top-mounted M2 screw lock that secures the connection on docks and enclosures with a locking port. It carries Thunderbolt 3, USB 3.2 Gen 2 data at 10Gbps and up to 100W Power Delivery 3.0 charging. The removable screw allows use with standard ports on laptops and external drives.

Suited for fixed desk setups

The screw lock prevents accidental disconnects on docking stations such as the DK31C3HDPD, making it ideal for permanent workstation cabling. Builders who need a longer reach or a non-locking cable for frequent plugging and unplugging should look at a different length or connector style.

Stable throughput over the full length

At 0.5m the cable maintains the full 10Gbps signalling rate without the signal degradation seen on longer passive runs. Nickel-plated 24-pin connectors, 32 AWG conductors and an aluminium-Mylar foil with 85% braid shield preserve data integrity and power delivery during sustained transfers and charging sessions.

Questions about this item

Do I need a device with a USB-C port that supports top screw locking for the M2 screw on this cable to engage?

Yes, the M2 screw (1.2" long) only locks into USB-C ports that have a top locking thread, such as the StarTech.com DK31C3HDPD dock; the screw is removable for use with standard USB-C ports on laptops or enclosures.

Will this 50cm cable still deliver 10Gbps and 100W power when I connect it to an older USB 3.1 Gen 1 (5Gbps) host or device?

The cable is rated for USB 3.1 Gen 2 at 10Gbps and 100W (5A) PD 3.0; when used with a Gen 1 host or device the link will negotiate down to 5Gbps, but the cable itself remains capable of the higher speed and power.

How can I verify that the cable is operating at its full 10Gbps data rate and 100W power delivery after I plug it in?

Check the host OS or dock firmware for a 10Gbps SuperSpeed USB 10Gbps connection status and confirm PD 3.0 5A/20V power negotiation; the cable also supports DP 1.4 Alt Mode up to 8K 30Hz video output as an additional indicator.
