براغي رأس سداسية M12-1.75 × 22 مم | فئة 8.8 فولاذ عادي | ملولبة بالكامل (600/عبوة)

The hex heads grabbed my 13mm socket cleanly with zero rounding, and the class 8.8 steel feels properly hardened for the frame bolting I did. For a full box of 600, the thread finish was consistent across every single screw I’ve used so far.

These came in one solid package, and the fully threaded length made them easy to cut down for a custom bracket. Worked fine with a standard socket, no stripped heads even on a few torqued-up installs.

Needed a batch for some heavy equipment assembly and these hex heads fit the wrenches perfectly. The Class 8.8 steel feels solid and the full threading made installation quick.
