Customer Reviews (4.8 / 5 · 5 reviews)

Avery T. ★★★★★

Finally found some bolts that thread smoothly all the way without galling—used them to secure a motor mount on my milling machine. The yellow zinc coating looks good and the hex head fit my socket perfectly.

Amelia H. ★★★★★

Used a socket driver on these and the hex heads held up perfectly, no stripping even when torqued tight. Nice to have a full 50-pack for my ongoing equipment builds.

Victoria M. ★★★★★

Had to replace some bolts on a piece of farm equipment and these hex heads fit my socket perfectly. The Grade 5 steel feels solid, and the yellow zinc coating looks clean and corrosion-resistant.
