John ★★★★★

The thermal black oxide finish looks great and held up perfectly when I torqued them down hard on a fixture plate. The nylon pellet in the tip locks them in place nicely, so vibration hasn’t loosened a single one.

Kevin ★★★★★

I needed a heavy-duty bolt for a jig I was building, and these 5/8-11 socket cap screws fit perfectly with no slop in the threads. The black oxide finish looks clean and professional, and the hex socket drive made installation quick with an Allen key. Handled the torque without any issue on my first

Matthew S. ★★★★★

These screws fit perfectly into the jig I’m building for a machining project, and the black oxide finish gives them a clean, professional look. The hex socket drive made installation quick with no stripping, and the nylon pellet locking feature is a nice touch for vibration resistance.
