8K HDMI Screw Lock Cable Assembly, HDMI 2.1 48Gbps, M3 Panel Screws
An hdmi screw lock cable adds a pair of M3 thumb screws that pull the plug shell onto the device jack, so cable load sits on metal threads rather than on connector friction. HDMI 2.1 48 Gbps class, 1 to 5 m, with panel coupler.
Overview
An hdmi screw lock cable exists because a standard HDMI connector is held in place by nothing but contact friction. In a control room, a broadcast gallery or an imaging display chain, a plug that walks out of its port is not a nuisance — it drops a source in front of an audience or in the middle of a procedure. This assembly adds a pair of M3 thumb screws that pull the plug shell onto the device jack, so the cable load is carried on metal threads instead of on the connector interface. It is offered with a matching panel coupler that carries the same retention through a rack or wall plate.

Friction is not retention
| Retention method | What holds it | Failure mode |
|---|---|---|
| Standard HDMI | Contact friction alone | Walks out over thermal cycles and vibration |
| Latching HDMI | A plastic catch on the shell | Catch wears, or snaps on a hard pull |
| Screw lock (this assembly) | M3 thumb screws into the device jack | Screws are the load path; the plug cannot move |
Friction also falls off as a port is cycled. A connector that felt firm on install day is a different connector after two years of re-patching, which is why the failures show up long after commissioning rather than during it.
M3 pitch and the panel cut-out
Screw pitch is the detail that most often trips up a retrofit. A plug that fits the pitch but not the post depth will not clamp, and a panel coupler that does not match the plate drilling will not bolt up. Confirm these four numbers before you order.
| Parameter | What this build uses | What to confirm on your side |
|---|---|---|
| Screw thread | M3 | Thread on the mating jack or panel coupler |
| Screw pitch (on center) | 25 mm | Spacing on the device jack |
| Post depth | Per mating hardware drawing | How far the screw can engage |
| Panel cut-out | Per coupler drawing | Plate thickness and drilling pattern |
We confirm the drawing against the mating hardware before production, because this is a part that is expensive to discover is 1 mm out.
Signal performance
- 48 Gbps class link, supporting 8K at 60 Hz and 4K at 240 Hz.
- HDR metadata pass-through.
- eARC return channel for audio fed back from a display or a sound system.
- HDCP 2.3 content protection supported by the link.
- Gold-plated HDMI contacts with nickel-plated M3 thumb screws.
These are the published figures for the HDMI 2.1 link class. The values your assembly is built and verified to are the ones on your drawing and confirmation order.
Assembly and panel options
Most installations use the two forms together: a cable assembly with screw-lock plugs, and a panel-mount coupler that carries the signal through a rack plate or a wall plate with the same screw retention on both faces.
- Screw-lock HDMI plug to screw-lock HDMI plug, in 1, 2, 3 and 5 m lengths.
- Panel-mount female-to-female coupler with a screw-lock face, offered with the plug assembly as a matched pair.
- Molded plug shell for general installation; metal shell where the cable is subject to abuse or repeated handling.
Our HDMI 8K panel coupler is the part that sits in the plate, and it is worth ordering both together so the two faces match.
Typical applications for this hdmi screw lock cable
- Control rooms and operations centers with sources that cannot drop mid-shift
- Broadcast and ProAV installations, including mobile and flyaway racks that get built and struck repeatedly
- Medical imaging displays where the cable is dressed and left alone for years
- Simulation and training systems, and LED video wall processors
- Industrial panels and machine HMIs, alongside our DisplayPort screw lock cable on the same plate
Ordering notes
Lengths are 1, 2, 3 and 5 m on passive copper. Beyond those distances we quote an active or fiber-based assembly instead, since at this bandwidth a passive copper run that is too long does not fail outright — it produces intermittent dropouts that are far more expensive to find. Jacket color, print legend and shell finish are configurable on production quantities.
Workmanship and testing
Workmanship on 8K HDMI Screw Lock builds follows IPC/WHMA-A-620 Class 3, the line is run under ISO 9001, and the termination range is 32 to 12 AWG. Every 8K unit is checked for 100% continuity and pinout before packing, and seal checking is quoted whenever an ingress rating is on the drawing.
Material declarations against RoHS and REACH are issued per project, alongside the dimensional and electrical reports agreed at quotation; see certifications, compliance and material declarations. Where your drawing names a UL style or another approval, the build follows your drawing and ships with the supporting document rather than a claim of our own. The strain relief and molded body are produced on tooling we cut ourselves see in-house mold making and overmold tooling so the tool is quoted separately, owned by you, and available for repeat runs years later. More background: our build-to-print process.
Custom builds and ordering
Quote 8K HDMI Screw Lock builds from 1 to 50 pcs and they ship in 3 working days. At volume the minimum is 500 pcs with 14 working days after approval. Tooling not already held adds around 10 working days. Your part number and labeling go on 8K shipments, and material certificates and first-article reports are available on request.

Frequently Asked Questions
Will M3 screws fit my existing jack?
Usually, but check the pitch and the post depth. We build to the common M3 on-center spacing and confirm the drawing against your mating hardware before production.
Can I get the panel coupler on its own?
Yes, and it is worth ordering both together so the screw faces and the drilling pattern match.
Why not just use a latching HDMI plug?
A plastic catch wears and can snap on a hard pull. Thumb screws carry the load on metal and cannot work loose unnoticed.
Can you build 10 m?
Not passively at this bandwidth. We quote an active or fiber-based assembly for longer runs rather than ship a lead that drops out intermittently.
