Customer Reviews (5.0 / 5 · 5 reviews)

Violet ★★★★★

Needed a solid batch of bolts for mounting motor mounts on a heavy-duty conveyor, and the partial threading on these Grade 5s made alignment a breeze. The zinc coating seems tough enough to resist shop moisture, and the hex heads gave my socket a good bite without slipping.

Madison ★★★★★

Bought these to rebuild a press, and the yellow zinc finish really helps them spin in easier without galling. The partial threading kept the clamping force where I needed it on the flange.

Steven C. ★★★★★

I was worried about stripping the hex head during a tight install, but the socket grip is excellent and the partial threads grabbed perfectly in my repair.
