Customer Reviews (4.8 / 5 · 5 reviews)

Michael ★★★★★

The hex heads on these bolts grab my socket wrench perfectly, no stripping or slipping. The yellow zinc coating on the Grade 8 steel seems really durable so far, definitely worth the price for 175 pieces.

Evelyn ★★★★★

I've been using these for heavy-duty frame repairs and the Grade 8 steel holds up perfectly under torque. The yellow zinc coating hasn't shown any rust after a few weeks outdoors. Exactly the length I needed for thick brackets.

Adam D. ★★★★★

I needed longer bolts for a farm equipment repair and these 6-1/2" Grade 8s were exactly the right length, the yellow zinc coating looks tough and should hold up outdoors.
