Customer Reviews (4.6 / 5 · 5 reviews)

Harper ★★★★★

I've been using these in my precision assembly rigs and the black oxide finish holds up much better than the zinc-coated ones I used before. The hex socket drive feels solid and hasn't stripped after multiple tightenings.

Brian ★★★★★

Installed these in a custom tool trolley and the black oxide finish looks clean while resisting rust so far. The hex drive bites perfectly with no cam-out. Solid hardware for the price.

Miles ★★★★★

Finally, a batch of socket head screws that are actually hardened properly—these 12.9 alloy steel ones don't strip out on me. The black oxide finish looks great and seems to resist rust better than the zinc-plated stuff I used before. Perfect for the jig I'm building.
