Customer Reviews (4.6 / 5 · 5 reviews)

Hannah M. ★★★★★

The thread fit was perfect in the jig I'm building, and the 10.9 steel rating gives me real confidence under load. The partial threading is a nice touch, making alignment way easier than a fully threaded bolt would've been.

Benjamin ★★★★★

Used these on a heavy press assembly and the Class 10.9 steel held up perfectly under full torque where lesser bolts would have snapped. The partially threaded design made aligning the nut much easier, too.

Stella ★★★★★

Finally, a bolt that doesn't strip the first time I put a wrench on it. The Class 10.9 steel feels incredibly sturdy, and the partial threading made aligning this 250mm screw in my press frame so much easier.
