Customer Reviews (4.6 / 5 · 5 reviews)

Kevin C. ★★★★★

Used these to bolt down a heavy-duty press at the shop, and the Grade L9 alloy steel held torque perfectly without any stretch. The hex head seated cleanly with a socket wrench on the first try. Solid fasteners for the price.

Eli ★★★★★

These bolts are noticeably heavier and better finished than the standard hardware store stuff. The yellow zinc coating looks consistent and should keep rust at bay. Installed them on a trailer hitch rebuild and the threads cut cleanly on the first pass.

Ella G. ★★★★★

Needed some heavy-duty bolts for a press repair, and these Grade L9 hex heads are absolute beasts. The yellow zinc finish is perfect, and having a full 60-pack means I’ve got spares for the next job.
