Customer Reviews (4.6 / 5 · 5 reviews)

Leo Y. ★★★★★

These 5/8-11 bolts threaded smoothly into our press frame without any binding, and the partial thread gave us just the right grip length. The heavy hex head was easy to wrench on in a tight spot, and they feel solid.

Ella ★★★★★

Had to replace some critical bolts on a press machine and these worked perfectly—the 2-1/2" length gave me just enough thread for a secure hold.

Mia ★★★★★

These bolts threaded smoothly into my trailer hitch mount without any binding. The Grade B steel seems sturdy enough for heavy equipment, and having 85 in the package was plenty for my project.
