M12-1.5 X 50mm براغي رأس سداسي | فئة 10.9 فولاذ مطلي بالزنك | ملولب بالكامل (50 / عبوة)

The threads cut cleanly into the steel frame I'm bolting together, and the hex head gave my ratchet a solid grip. Fit perfectly in the pre-tapped holes without any binding. Just what I needed for heavy equipment assembly.

Used these to secure a heavy-duty conveyor frame, and the zinc plating held up fine against a little moisture. The fully threaded design made it easy to get full bite into the nut, and the hex head fit a socket perfectly without stripping.

Installed these on a hydraulic press project last week and the fully threaded design made alignment a breeze. Heads fit a standard 19mm socket perfectly without any stripping.
