براغي رأس سداسية M20-2.5 × 65 مم | فولاذ فئة 8.8 مطلي بالزنك | ملولبة بالكامل (25/عبوة)

Used these to mount a heavy press in the shop and the hex head made torquing them down with a socket really easy. The zinc plating held up well even with some wrench slip.

Threads were clean and smooth right out of the bag, and the zinc coating looks even all over. The hex heads seated nicely with a socket wrench on a heavy jig I'm bolting together, no stripped corners or wobble. Exactly the fastening confidence I want for 8.8 grade.

Installed these on a press frame I'm building; the 8.8 rating gives me confidence the heads won't strip under torque. The zinc plating looks clean and even, no burrs on the threads out of the package.
