Customer Reviews (4.6 / 5 · 5 reviews)

Leo ★★★★★

I’ve used these on a couple of tooling fixtures and the heads sit flush without any wobble—the hex drive grips the key perfectly. The black oxide finish has held up through assembly and disassembly without any rust or wear so far. For a 50-pack at this price, they’re a solid buy for any shop.

Ellie Z. ★★★★★

These threads are cleanly cut and the black oxide finish holds up nicely without flaking during installation. The socket drive seated the wrench firmly even at higher torque, and all fifty had consistent thread depth. Good value for jig work.

Harper ★★★★★

Finally a cap screw that fits tight without wobbling—the threads are crisp and clean. Used them to repair a jig on my milling machine and they held perfectly with no stripping. For the price per pack, you can't beat the quality.
