براغي رأس أسطوانية M12-1.25 × 20 مم | محرك سداسي | كاملة الخيوط | فئة 12.9 من سبائك الصلب مع أكسيد أسود حراري (100/عبوة)

The hex drive on these M12 bolts grabs the allen key perfectly with no wobble, and the black oxide finish looks consistent across all 100 pieces. I used them to rebuild a jig fixture for my mill and they torqued down evenly without any binding.

These came out of the bag with a flawless, matte black finish and the threads are immaculate on every single one. I used a dozen for a jig build and the 12.9 alloy steel feel rock solid under the wrench. Exactly what I needed for the price.

I needed some high-strength fasteners for a jig I’m building, and these M12 socket cap screws threaded in smoothly without any binding. The hex socket drive made installation easy with a standard Allen key, and the 100-pack gives plenty of spares.
