Customer Reviews (4.4 / 5 · 5 reviews)

Grace ★★★★★

The knurled cup point really bites into the shaft without stripping, and the hex socket held up through repeated torque adjustments in a cramped motor mount. For a hundred pieces at this price, the alloy steel feels solid and the threads ran clean all day.

Riley O. ★★★★★

Installed these to lock down a jig on my drill press, and they hold fast without slipping. The hex socket lets you really torque them down in cramped spots where a regular wrench won't fit.

Sophia ★★★★★

The knurled cup point bites into soft metal way better than a flat tip, so my setup finally stopped slipping. The hex drive makes them easy to torque down even in awkward spots, and all 100 arrived clean with no burrs.
