Customer Reviews (4.6 / 5 · 5 reviews)

Avery ★★★★★

They fit perfectly in my impact socket and the yellow zinc finish looks good against the steel. Used them to rebuild a small conveyor belt drive and all 800 threaded smoothly into place.

Benjamin O. ★★★★★

Packed a full 800 into my tool box, and every one of these Grade 5 bolts threaded smoothly into the steel frame without any binding. The yellow zinc coating looks solid and should hold up fine in a slightly damp shop.

Charlotte S. ★★★★★

The hex heads on these bolts grip the socket perfectly, so I didn't have to worry about any stripping during assembly. Pack of 800 is plenty to finish a few equipment racks, and the yellow zinc finish seems solid.
