Customer Reviews (4.6 / 5 · 5 reviews)

Adam ★★★★★

I needed these for a heavy equipment repair and the hex head gave my socket wrench a solid bite without stripping. The Grade 5 steel feels tough enough to handle the torque, and the yellow zinc coating is a nice bonus for corrosion resistance.

Elizabeth G. ★★★★★

The partially threaded design made installing these on my press table much easier, and the yellow zinc has a nice consistent finish across all 125 pieces. No stripped heads or bad threads in the whole batch.

Ava ★★★★★

Was a bit skeptical about buying hardware in bulk online, but these hex bolts threaded on nicely without any binding. The yellow zinc coating looks consistent across all 125 pieces.
