Customer Reviews (4.4 / 5 · 5 reviews)

Steven E. ★★★★★

The thermal black oxide finish took the torque I threw at them without a hint of galling, and the hex socket seated perfectly with my Allen key. Threads were clean and consistent out of the box, which made assembly on my tooling fixture a quick, frustration-free job.

John B. ★★★★★

I needed a full box of these for a jig build and the black oxide finish held up perfectly against the cutting oil without any surface rust. The 5/8-18 thread cut cleanly into my fixture plate, and the 1-1/2" length was just right for the clamping setup.

Avery ★★★★★

The hex drive on these 5/8-18 socket cap screws is super crisp, making installation smooth with no stripping. I've used them on a few jigs so far, and the black oxide finish seems tough and consistent across the whole batch.
