Customer Reviews (4.6 / 5 · 5 reviews)

Alexander S. ★★★★★

Bought these for a jig I’m building, and the class 10.9 rating gives me confidence they won’t strip under load. The partial threading worked perfectly for clamping two plates together, and the 925 count means I’ve got spares for the next few projects.

Penelope C. ★★★★★

The hex head fits my socket perfectly, and the Class 10.9 steel feels solid for the price. Needed these for a jig I'm building, and they seated cleanly without stripping.

Emma ★★★★★

Got the whole box of 925 and every single one came out of the bag with a consistent, clean finish—no burrs or crooked threads. The 10.9 hardness makes them feel solidly built for the machine frame I'm bolting together, and the partial threading gives just the right grip depth.
