Customer Reviews (4.8 / 5 · 5 reviews)

Hannah R. ★★★★★

The hex head on these cap screws fits my socket perfectly, making installation on a conveyor frame quick and stable. The class 8.8 steel feels solid and should hold up well under constant vibration.

Charlotte ★★★★★

The threading is clean and the hex head seated perfectly in my socket wrench without any stripping. These Class 8.8 bolts feel solid for the price, and the 25-pack covered my whole project with extras to spare.

Henry ★★★★★

I needed a full-threaded 55mm bolt for a heavy-duty jig I’m building, and these M16s fit perfectly with a solid hex drive. The 8.8 steel feels sturdy enough for the load, and the threading is clean all the way down. Exactly what I expected for the price.
