براغي رأس مقبس M6-1 × 60 مم | محرك مقبس سداسي | خيط جزئي | فئة 12.9 سبيكة فولاذ مؤكسد أسود حراريًا (200/عبوة)

I needed a batch of M6-1 x 60mm screws for a custom jig, and the partially threaded design made alignment so much easier than fully threaded ones I’ve used before. The hex socket drive held up well under my impact driver without stripping. These are solid for precision work.

The black oxide coating on these screws gives them a nice, uniform finish that feels durable. They threaded smoothly into my precision assembly without any binding issues.

Used these for a jig build and the 12.9 grade really holds torque without stripping. The partially threaded shank made alignment easier than I expected for precision work.
