براغي رأس كبس M10-1.5 × 40 مم | محرك سداسي | كامل الخيوط | فولاذ سبيكة فئة 8.8 مؤكسد أسود حراري (100/عبوة)

These fit perfectly in my jig build, and the hex socket made tightening them in tight spots much easier than a standard bolt. The 40mm length was just what I needed for a clean, secure hold.

I’ve used these in a few jigs and precision fixtures, and the hex socket drive sits perfectly flush with the counterbore every time. The thermal black oxide coating held up well against the shop oil and grime, no rust or discoloration after a week of use. Exactly what I needed for the price.

Installed a set of these for a jig build yesterday and the hex socket drive made torquing them down much easier than allen heads. The black oxide finish held up well against the grime and metal shavings in my workshop.
