Customer Reviews (4.8 / 5 · 5 reviews)

Edward ★★★★★

I needed a full set of these for mounting some heavy equipment, and the fully threaded design made alignment much easier. The class 8.8 steel feels solid, and the 25-pack was exactly what I needed for the job.

Sophia ★★★★★

The hex head on these M18 bolts grabs the socket perfectly with no slipping. Fully threaded along the 40mm length made them easy to cinch down tight on my jig. A solid pack for the price.

Natalie ★★★★★

These are the right thread pitch for the M18 hardware I'm using, and the class 8.8 steel has held up fine under a decent amount of torque so far. The fully threaded length gave me plenty of grip for my assembly.
