براغي ذات رأس سداسي M18-2.5 X 75mm | فئة 8.8 فولاذ مطلي بالزنك | ملولبة بالكامل (20 قطعة/عبوة)

Threaded them into a jig I’m building and the class 8.8 steel holds torque like a champ without stripping. Full threads made engagement feel solid from the first turn, and the zinc coat seems even enough to resist a few scratches.

The zinc plating on these screws is nice and even, and the hex heads held up perfectly under my impact driver without stripping. I used these on a heavy equipment frame repair and the class 8.8 strength gave me confidence in the joint. This pack of 20 will last me through several projects.

Swapped out the cheap bolts on my press jig for these and the fully threaded grip makes a world of difference. The hex heads sit flush with a socket and the zinc finish hasn’t marred under a couple of heavy tightening cycles.
