Customer Reviews (4.6 / 5 · 5 reviews)

Carter ★★★★★

Installing these on a custom jig for some repeat drilling was a breeze — the black oxide finish holds up nicely without any galling. Each screw seated perfectly flush without stripping.

Owen P. ★★★★★

I needed a solid batch for a small robotics jig, and these hex socket screws fit perfectly with no stripped threads during install. The black oxide finish is smooth and uniform across all 900 pieces.

Violet L. ★★★★★

I needed a solid batch for jig assembly and these hex heads seated perfectly with no stripped threads. The thermal black oxide finish seems tough and consistent across the whole pack, so these should hold up well in fixtures.
