Nicholas ★★★★★

The black oxide finish on these M2.5 screws gives them a nice, uniform look and they thread smoothly into my jigs without any binding. For a bulk pack of 600 Class 10.9 fasteners, the price is hard to beat and they're holding up great in my tooling setups.

Hazel N. ★★★★★

I needed a reliable batch of small screws for a precision jig assembly, and these M2.5 button heads are consistently threaded with no burs. The hex socket drive fits snugly, making installation quick.

Emma X. ★★★★★

I was a bit skeptical about the hex socket holding up at this small size, but they drive cleanly into aluminum without stripping. The black oxide finish gives them a nice, uniform look for the custom fixture I built.
