## Description

This locking USB C cable is built for stable connections in docking setups and mobile workstations. It combines a compact 20 inch form factor with side screw locking to prevent accidental disconnects, and it supports fast charging and high speed data transfer so you can rely on it during long work sessions. The cable is useful for docking stations, external drive enclosures, and laptops that need secure USB-C links, and it handles power delivery and video passthrough with a focus on durability.

## Key points

The cable supports USB 3.2 Gen 2 SuperSpeed for up to 10 Gbps transfers and carries DisplayPort Alt Mode signals up to 8K at 30 Hz, which helps when you need a single cable for docking and display. It also delivers up to 100 W power delivery at 20 V and 5 A, so charging a compatible laptop is possible while transferring data. Tested for more than 10,000 insertions and over 4,000 120 degree flex cycles, the build is aimed at repeated use in portable and stationary setups. **StarTech.com 20" (50cm) Side Screw Locking USB C Cable** appears in contexts where cable retention and signal integrity matter, for instance in shared workspaces or rack installations. The dual screw lock design uses removable M2 knurled screws for a firmer attachment, reducing the risk of accidental unplugging during transport or maintenance. ⚙️

## Specifications

- Name: **StarTech.com 20" (50cm) Side Screw Locking USB C Cable**
- Size: 50cm
- Power: 100W (5A) PD 3.0
- Display: DP Alt Mode up to 8K 30Hz
- Resolution: 8K 30Hz
- Material: TPE with Al-Mylar and braided EMI shielding
- What’s included: removable M2 knurled screw

## Why it makes sense

Durability and signal integrity are the main selling points. The cable uses 32 AWG conductors and layered shielding to reduce interference, which matters when you drive high bandwidth displays or move large files. The TPE sheath is described as flexible and RoHS compliant, offering a softer feel than rigid jackets and easing routing behind desks. You’ll notice fewer accidental disconnects thanks to the side screw locking mechanism, and the knurled screw design makes installation and removal straightforward without tools in many cases. 🔧

## Best use cases

This cord is practical for technicians who work with docking stations and external storage because it secures the connection and supports both power and video. It suits mobile professionals who plug and unplug gear often and need a compact cable that survives repeated handling. It may not be necessary for casual users who rarely move devices or for setups that do not require locked connections, but where secure attachment and combined PD and DP support are required this cable offers a clear functional benefit.
