براغي كاب سداسية M10-1.5 × 85mm | محرك سداسي | خيط جزئي | فولاذ سبيكة كلاس 12.9 أكسيد أسود حراري (50/عبوة)

I needed a batch of strong bolts for a tooling jig I’m building, and these 12.9 alloy steel screws handle the load without any flex. The partial threading let me get a solid grip on the clamp plate, and the black oxide coating looks clean and durable.

The black oxide finish on these M10 bolts handled a machine tool jig application without any galling or rust marks after a week. The hex socket drive seated perfectly with my standard allen key, and the partially threaded shaft made alignment a breeze for my assembly. Glad I went with the Class 12.9

Needed some high-strength bolts for a press jig I’m building, and the 12.9 alloy steel on these feels rock-solid. The black oxide finish is a nice touch, too—should hold up well against light rust in the shop.
