Customer Reviews (5.0 / 5 · 5 reviews)

Chloe V. ★★★★★

The hex heads fit my socket perfectly with no wobble, and the yellow zinc finish looks clean and rust-resistant. I used a full bag on a jig assembly and every bolt threaded smooth without any binding.

David Z. ★★★★★

The threading runs all the way down, so I didn’t need to fuss with partial engagement when bolting a bracket to my workbench. The yellow zinc coating looks uniform, and the Grade 5 steel feels sturdy under a wrench. These are solid for general assembly, no complaints here.

Ava ★★★★★

The hex heads on these bolts fit my socket perfectly with no wobble, and the yellow zinc coating looks great against the steel. I used them to rebuild a small engine stand and every single one threaded in smoothly.
