Customer Reviews (4.8 / 5 · 5 reviews)

Emma O. ★★★★★

I needed a few for a jig I was building and these fit the hex drive perfectly without stripping. The 1/2-13 thread engaged smoothly into the tapped hole.

Victoria ★★★★★

The black oxide finish on these screws is really consistent and seems like it'll hold up well in my jig setup. Threads ran smooth with no binding, and the hex socket grabbed tight without stripping. Exactly what I needed for a tooling repair job.

George A. ★★★★★

I needed a fresh batch for a fixture rebuild, and the hex socket drive on these made installation in a tight spot a breeze. The 50-piece pack gives me plenty of extras for the shop.
