Customer Reviews (4.6 / 5 · 5 reviews)

Ryan I. ★★★★★

These hex bolts threaded smoothly into my equipment frame with no binding at all. The Grade 5 yellow zinc finish looks clean and should resist corrosion well. I've already ordered another box for the next batch of assemblies.

Elizabeth ★★★★★

Had a small job tightening some industrial shelving and these hex heads fit my socket perfectly without any stripping. The yellow zinc finish seems like it will hold up well against occasional moisture.

Mia ★★★★★

These bit perfectly into the bracket of my small milling machine, the Grade 5 steel feels much sturdier than the hardware store stuff. I was worried about the yellow zinc looking cheap, but it actually has a clean, even finish.
