Hexalobular (Torx) Anti-Loosening Screw
The Hexalobular (Torx) Anti-Loosening Screw is built for miniature products that vibrate. It is cold-headed from premium alloy steel — a process that forms the part by material displacement and strengthens it in the process — and the thread is supplied with a locking element already applied.
That locking element is either a nylon patch or an adhesive coating. Both raise friction in the thread so the screw cannot unwind on its own, and both are dry, pre-applied treatments: nothing has to be dispensed on the line and no residue is left inside the assembly. The nylon-patch version can also be reused several times without losing holding force.
The Torx (hexalobular) recess transfers torque reliably and resists cam-out, which keeps automated screwdriving consistent. Combined with the anti-loosening treatment, it delivers dependable connection reliability in high-vibration environments — in small devices where a loosened screw means a returned product.
Extensively used in consumer electronics, UAVs and drones, automotive interiors and smart equipment, these screws are engineered for the precision fastening and long-term anti-loosening requirements of miniaturized devices operating under high-frequency vibration and impact.
They suit any small assembly produced on automated lines where a reliable, reusable locking screw is preferred over liquid adhesives.
