MS16995-26 | براغي رأس تجويفي عسكرية | محرك تجويف سداسي | فولاذ سبائكي (100 / عبوة)

I used these in a jig at the shop and the alloy steel held up perfectly under repeated torque. The hex socket drive fits my wrench snugly without any slipping, even after a few dozen uses.

I needed a bunch for a new fixture at work, and these hex socket drive screws threaded in smoothly without any binding. The alloy steel feels plenty tough for the tooling loads we put on them.

Bought a pack of 100 for a jig I’m building, and the hex socket drive seats perfectly every time—no stripping even after torquing them down hard. The alloy steel feels solid, and having a full box on hand beats running to the hardware store mid-project.
