Customer Reviews (5.0 / 5 · 5 reviews)

Harper ★★★★★

The black oxide finish looks sharp and resists fingerprints better than I expected during assembly. These have been holding tight in my jig setup for weeks without any loosening or wear on the threads.

Grace ★★★★★

The hex socket drive seated perfectly on my Allen key with zero wobble, and the 12.9 alloy steel feels seriously tough. I used them to bolt down a jig plate and they torqued up clean without stripping.

Penelope ★★★★★

The black oxide finish gives them a nice, even look and they seated cleanly into my jig without any binding. For a 12.9-grade screw at this price, the threads are surprisingly crisp and the hex socket grabbed my allen key on the first try.
