براغي رأس سداسية M12-1.25 × 100mm | فولاذ فئة 8.8 عادي | ملولبة جزئيًا (50 / عبوة)

These threads let me torque them down properly with a socket, and the partial threading grabs just right for my equipment jig. Fifty in the pack means I've got spares for the next project, too.

I needed a dozen to finish a hydraulic cylinder rebuild, and these were exactly the right size for the bolt holes I was threading into. The hex heads grip well with a socket, and the partial threading made assembly a lot easier than fully threaded bolts would have.

The partially threaded shank on these M12 screws made all the difference for my press brake mount—plenty of grip without bottoming out. The hex heads seated cleanly with a socket wrench, and the Class 8.8 steel feels solid for the money.
