Customer Reviews (4.8 / 5 · 5 reviews)

Owen ★★★★★

Pulled one of these out of my socket set to swap a stripped screw on a jig, and the hex drive bit held perfectly without any cam-out. The alloy steel feels solid, and the knurled cup point seated flush in the countersink.

Lucy E. ★★★★★

The knurled cup point really grabs on tight when fastening into softer materials, and I haven't had one strip yet. Used a few in a jig build, and the hex socket held up fine under repeated high-torque adjustments.

Amelia ★★★★★

These knurled cup points really bite into the shaft, and the hex socket made it easy to tighten them with my Allen key even in a cramped spot. All 100 screws looked clean and consistent out of the package.
