0.6mm CM Ultra-Thin Head Serrated Anti-Loosening Micro Screw
This micro screw targets the tightest internal spaces in compact electronics. Its head is only 0.6mm thick, an ultra-low profile that frees vertical space inside slim enclosures without giving up clamping function.
Locking is achieved mechanically. A precision serrated pattern on the underside of the head increases friction against the mating surface when the screw is tightened, so rotation is resisted and vibration cannot gradually unwind the joint. Because no chemical adhesive is involved, the screw leaves no residue, needs no cure time and can be reworked cleanly.
The threads are produced by micro-diameter cold-heading, which forms full, complete thread profiles even at small sizes. Consistent thread form delivers predictable engagement and holding force, which is what makes a miniature fastener dependable in devices that vibrate constantly.
Extensively used in smart wearables, ultra-thin smartphone frames, precision micro-motors and minimally invasive medical instruments, this screw is ideal for internal structures with extremely tight tolerances.
It meets the dual requirements of modern micro-manufacturing — minimal height and dependable long-term retention — and suits sensor mounts, micro-drive units and compact optical assemblies.
