Ellie ★★★★★

I needed a full bag of M3 socket cap screws for a jig build and these 316 stainless ones came out of the box uniform and clean, threads all sharp. The hex socket bites well with a 2mm driver, and 600 pieces means I won't be reordering for a while. Great value for precision work.

Christopher ★★★★★

The hex socket drive on these 316 stainless screws makes them a breeze to work with in tight spots. They feel solid and corrosion-resistant, perfect for my jig builds.

Sebastian S. ★★★★★

I needed a bulk pack of M3 screws for some precision tooling, and these 316 stainless ones feel far more robust than the regular 18-8 hardware I've used before. The hex socket drive engages cleanly without any stripping, even on repeated fastening. 600 pieces in the bag should last me through severa
