Customer Reviews (5.0 / 5 · 5 reviews)

Penelope ★★★★★

These went into a jig fixture I’m building and the threads cut clean with no galling. The thermal black oxide coating gives them a uniform, non-glare finish that’s held up through a few assembly cycles.

Alexander ★★★★★

The black oxide finish on these bolts looks sharp and handled the chuck on my mill without slipping. Threads were clean and seated smoothly into my fixture plate, no binding or galling. Solid pack of ten for the shop, I'll grab another when these run low.

Harper U. ★★★★★

I needed longer 3/4-10 bolts for a jig I was building, and these 7-1/2" socket cap screws were exactly what I was looking for. The hex socket drive made them easy to torque down with an Allen key, and the black oxide finish looks clean and professional.
