براغي كاب مقبس M10-1.25 × 35 مم | محرك مقبس سداسي | ملولب بالكامل | فولاذ سبائكي فئة 12.9 مطلي بالزنك (100/عبوة)

I needed a batch of high-strength fasteners for a jig rebuild, and these 12.9 alloy steel screws torqued down perfectly without any stripping. The zinc coating is even and should resist corrosion well in my shop.

These replaced some worn-out button heads on a jig fixture, and the 12.9 hardness made torquing them to spec feel much more reliable than the old 8.8s. Packed a hundred, so I've got plenty left for the next project.

Zinc plating is holding up nicely on the threads after a week of use in a jig I built, and the fully threaded shaft made spacing adjustments a breeze. These socket cap screws cinch down with a satisfying solid feel, and the 12.9 alloy steel gives me real confidence in the clamping force.
