Torx Screws with Nylon Patch Anti-Tamper & Anti-Loose Furniture
Our torx screw series includes pan head, flange head, and cylindrical head types in M3, M4, M6 sizes, with anti-loose...
Our hex socket screw series includes cap head, flange head, and pan head types in standard M5 sizes, with optional anti-loose nylon patch coating. Available in zinc-plated steel and brass, they are designed for electric meter internal components, terminal blocks, and panel fastening. The nylon patch provides vibration-resistant locking, while the hex drive ensures stable torque and anti-tamper performance, making them ideal for long-term reliable connections in power metering equipment.

1.Integrated flange washer design for even pressure distribution: The built-in flange washer spreads tightening force to avoid damaging the meter’s plastic or metal panel surface.
2.Optional nylon patch anti-loose coating: The blue nylon patch creates a friction lock to resist loosening caused by long-term equipment vibration and temperature changes.
3.Two functional material options for diverse scenarios: Zinc-plated steel for general assembly and brass for high-conductivity terminal connection applications.
4.Precision hex socket drive for stable torque: The Allen drive ensures efficient torque transmission and reduces the risk of cam-out during installation.
5.Diversified head styles to match different structures: Cylindrical cap, flange, and pan head designs adapt to various PCB, terminal block, and meter shell assembly needs.
Highly reliable long-term connection performance
The nylon patch anti-loose technology maintains stable clamping force under vibration, reducing terminal overheating risks.
Excellent conductivity and corrosion resistance
Brass screws are ideal for terminal connections, while zinc-plated steel offers reliable rust protection for cabinet environments.
