Customer Reviews (4.6 / 5 · 5 reviews)

Lily ★★★★★

Ordered these for a precision jig assembly and the hex socket drive made it easy to get a solid grip even in tight spots. The 10.9 grade steel feels strong enough for industrial use, and no stripped heads after torquing down all 1200 pieces.

Alexander S. ★★★★★

The black oxide finish on these screws is so consistent and smooth that they thread into my precision assemblies without any binding at all. I’ve used cheaper packs before where the hex sockets stripped on the first turn, but these class 10.9 heads are holding up perfectly under repeated torque.

Violet ★★★★★

Installed these into a jig for a small CNC project and every single one seated perfectly. The hex socket drive makes them easy to torque down without stripping, and the 1200 count will last me years.
