Customer Reviews (5.0 / 5 · 5 reviews)

Henry ★★★★★

Needed to replace a set on an old machine press and these hex heads matched the thread pitch exactly. The 8.8 steel feels hefty and the partial threading made alignment much easier than fully threaded bolts.

Stella J. ★★★★★

Fit perfectly on the drive shaft of my press brake—the partially threaded section made alignment a breeze. These M30s are hefty and the Class 8.8 steel feels solid under a heavy wrench.

Mia ★★★★★

The threads cut cleanly and the hex heads took a socket without any rounding, even at full torque. For the price per piece, these class 8.8 bolts feel like a solid deal for heavy equipment repairs.
