Customer Reviews (4.8 / 5 · 5 reviews)

Jacob B. ★★★★★

These threads are perfectly formed and the hex heads gripped my socket without any wobble. I used them to rebuild a press and every single one seated smoothly.

Owen W. ★★★★★

The yellow zinc finish is a nice touch—these bolts look clean out of the package and the hex heads seat perfectly with a socket. I used them to secure a heavy base plate and the fully threaded length gave me plenty of grip. Solid batch for the price.

Stella N. ★★★★★

I needed Grade L9 for a high-torque application, and these 5/8-11 bolts threaded smoothly into place without any binding. The hex head gave my socket a solid grip—exactly what I was hoping for.
