براغي رأس مقبس M10-1.5 × 75 مم | محرك مقبس سداسي | جزئية الخيوط | سبيكة فولاذ درجة 12.9 أكسيد أسود حراري (100 / عبوة)

Needed a set of high-strength bolts for a press jig rebuild, and these 12.9 alloy screws torqued down perfectly without any stripping—black oxide finish gave them a nice uniform look, too.

I've been building a custom welding fixture and the partially threaded design on these M10 screws made alignment much easier. The black oxide finish looks professional and the hex drive seated firmly without any stripping.

Used a full pack on a pair of heavy jigs for a machine table and every single one seated cleanly without any galling, the black oxide finish feels properly slick. Threads are cut sharp and the 75mm length is just right for clamping stacked plates.
