Customer Reviews (4.6 / 5 · 5 reviews)

Penelope ★★★★★

Used these to fasten a heavy-duty conveyor bracket at work and the 120mm length gave just the right grip depth. The partially threaded body made alignment much easier than fully threaded bolts would have.

Ruby J. ★★★★★

The yellow zinc finish looks properly applied, even coating across all five heads with no bare spots. I used the partially threaded length for a jig where I needed full grip on the first 60mm and it held up fine under heavy torque.

Chloe A. ★★★★★

For a 120mm bolt this size, the class 10.9 steel feels reassuringly solid, and the yellow zinc coating looks even in person. Threads are crisp and the hex head sits perfectly in a 30mm socket, no wobble. I've used three so far on a press frame and they torqued down cleanly without any galling.
