Was a bit skeptical about the black oxide holding up on these heavy-duty bolts, but after a full day in a milling fixture they still look great. The hex socket drive made it easy to torque them down tight without stripping.

These bolts threaded into my jig perfectly without any binding, and the black oxide finish holds up well to shop oil and grime. Really solid feel for heavy-duty tooling work.

Installed a dozen of these on a heavy tooling fixture and the hex socket drive made torquing them down in tight spots much easier. The black oxide finish seems durable and hasn't chipped during assembly. Only wish they came with a few extras in the pack.
