براغي ذات رأس أسطواني M12 × 35 مم | محرك سداسي منخفض الرأس | فولاد سبائكي فئة 8.8 (50 / عبوة)

I needed low-profile fasteners for a jig I was building, and the 8.8 alloy steel in these M12 screws gives me confidence they'll hold up under repeated torque. The hex socket drive seated perfectly with my Allen key, and the 50-pack was exactly what I required for the project.

The hex socket drive made seating these into my fixture plates a breeze, and the 35mm length was spot-on for the tooling block I was assembling. Class 8.8 alloy steel feels plenty rigid for the clamping loads I’ve put on them so far.

I used these to rework a jig for my CNC fixture table and the hex socket drive made torquing them down with a ball-end driver way easier than I expected. The class 8.8 alloy steel feels plenty rigid for the precision assembly work I’m doing, and all fifty came in clean, with threads free of any burr
