Customer Reviews (4.4 / 5 · 5 reviews)

Zoe ★★★★★

Installed these in a jig for a repeat drilling operation and they seated perfectly with no wobble. The hex socket gives solid bite without stripping, even under frequent tightening cycles.

Abigail I. ★★★★★

I needed exactly these for a small jig I was building, and the hex socket drive made tightening them in tight spots a breeze. The thermal black oxide finish looks solid and should hold up well on the shop tools.

Chloe N. ★★★★★

Finally, a pack of #4-48 screws that actually have consistent threads and a strong black oxide finish—I used these on a small jig and they seated perfectly every time. The hex socket drive made installation a breeze with no stripped heads.
