Smaller than a grain.
Held to microns.
At M0.5, a single thread chamfer decides whether a product survives. Micro precision fastening combines cold-heading, rolled threads and 100% inspection into tiny parts you can trust.
Where tolerance is the whole product
A micro screw that is 10 microns off can jam a feeder, crack a board or fail a medical device. We cold-head and roll threads to hold head diameter, under-head radius and thread form inside tight limits, then screen every part on optical CCD inspection so the bad pieces never reach your line.
- M0.5-M2 micro screws with rolled threads for strength and fatigue life
- Precision pins, spacers and custom micro components
- 100% CCD visual inspection for head, thread and surface defects
- Material options including non-magnetic brass and stainless

We run M0.5 and M0.6 in volume with rolled threads and full CCD inspection, holding critical dimensions to tight tolerances and feeding them reliably on automation.
100% optical CCD inspection screens each part for head, thread and surface defects, alongside dimensional SPC - so defect levels are measured, not hoped for.
Yes. Send the mechanism and envelope; we form the pin, spacer or screw cold-headed and prove it with samples and inspection data.
