Aurora ★★★★★

I needed screws that could handle high torque without stripping, and these M10-1.25 socket caps with the thermal black oxide finish fit perfectly in my jig setup. The hex socket drive grabbed cleanly, and the partially threaded design made assembly a breeze.

Joseph ★★★★★

The 12.9 grade hardness is exactly what I needed for my jig assembly—no stripping even under heavy torque. The 55mm length gave me just enough thread engagement for a thick mounting plate, and they came in a solid box of 100.

Eli O. ★★★★★

The black oxide finish on these has held up perfectly on my jig hardware, no rust after weeks of shop use. The partial threading gives just enough grip depth without bottoming out in blind holes, and the hex drive seated firmly with no cam-out.
