Customer Reviews (4.8 / 5 · 5 reviews)

Jacob M. ★★★★★

The black oxide finish on these M3 screws looks great and seems durable, and they drive perfectly into my 3D printed jigs without stripping. Exactly what I needed for precise assemblies.

Olivia E. ★★★★★

I needed a bulk pack of M3 screws for a jig project, and these Class 12.9 alloy steel bolts feel much tougher than the typical ones I've handled. The black oxide coating gives them a nice, uniform look that resists scratches.

Adam ★★★★★

The hex socket drive seated cleanly on my driver with zero wobble, and the black oxide finish gives them a consistent, non-glare look across all 600 pieces. Threads ran smoothly into my aluminum fixture without any binding, and the 12.9 grade feels reassuringly rigid for the price.
