براغي رأس أسطوانية M12-1.75 × 80 مم | محرك سداسي | جزئي الخيط | فئة 8.8 فولاد سبائكي مطلي بالزنك (25 / عبوة)

I needed some strong bolts for a jig on my milling machine, and these 80mm partially threaded ones did the trick. The zinc plating looks clean and durable, and the threads engaged smoothly without binding.

Used these for a new workbench build and the partially threaded design made alignment much easier than full thread bolts. The zinc coating looks clean and should hold up well in my garage. Solid fasteners for the price.

I had to replace some worn bolts on a jig, and these M12-1.75 x 80mm screws fit perfectly into the tight spots. The partially threaded design held everything securely under moderate load, so I'll definitely order more.
