Daniel Y. ★★★★★

Swapped out some cheaper bolts on a press tool and these seated perfectly, the black oxide finish looks sharp and the hex drive grips without stripping. Threads ran smooth all the way down, no binding in the tapped holes. Solid choice for jigs where you need repeatable torque.

William ★★★★★

Installed these in a jig setup yesterday and the hex socket drive seated perfectly without any rounding. The thermal black oxide coating has a nice even finish, and the 80mm length gave me just the right amount of thread engagement.

Madison ★★★★★

The 80mm length on these socket cap screws is just what I needed for a heavy-duty jig repair, and the hex drive held torque perfectly without stripping.
