براغي رأس سداسي M12-1.75 × 120 مم | فئة 10.9 فولاذ زنك أصفر | ملولبة بالكامل (225/عبوة)

The hex head on these M12 screws fits my socket perfectly with zero wobble, and the yellow zinc finish looks clean. I needed a full box for a frame assembly and every single one threaded smoothly without binding. Solid purchase for the price.

Installed a dozen of these on a heavy equipment jig and not a single one stripped during torquing. The class 10.9 steel gives real peace of mind for structural loads.

The yellow zinc finish is holding up nicely on these fully threaded 10.9s—no flaking after a week of outdoor use. I torqued a few to spec on a jig frame and the hex heads didn't strip, which is exactly what I needed.
