Customer Reviews (4.8 / 5 · 5 reviews)

Emily ★★★★★

The hex head on these screws gave my socket a solid bite without any slipping. The yellow zinc finish looks factory-fresh and the partial threading made alignment a breeze on my jig. These feel like they'll outlast the equipment I'm using them on.

William W. ★★★★★

The yellow zinc coating on these Grade L9 bolts held up perfectly during assembly, no galling or chipping even with a heavy impact wrench. The partial threads made alignment in the equipment frame much easier than I expected. For a 20-pack of this size, the price feels right.

Leo ★★★★★

Had to torque these down pretty hard on a heavy-duty jig I’m building, and the hex head held up without any stripping—definitely feels like proper USA steel. The yellow zinc coating is a nice touch for a bit of rust resistance in the shop too.
