Customer Reviews (4.6 / 5 · 5 reviews)

Madison ★★★★★

Installed a full set of these on a drill jig table, and the black oxide finish holds up well to chip buildup. Threads are crisp and the hex drive seated perfectly in my wrench.

Steven ★★★★★

These bolts went straight into a jig I was machining, and the black oxide finish feels tough and even across every single one. Class 12.9 strength means I don't have to second-guess them under load.

Robert Z. ★★★★★

Needed these for a jig I was building, and the 12.9 alloy steel feels way more solid than the regular stuff I've used before. The hex drive seated perfectly without any stripping.
