براغي رأس مقبس M6-1 × 45 مم | محرك مقبس سداسي | خيط جزئي | فئة 8.8 فولاد سبائك أكسيد أسود حراري (400 / علبة)

The partially threaded design on these M6 screws made aligning them into my jig setup much easier than fully threaded ones. The black oxide finish seems consistent across all 400 pieces, which is exactly what I needed for a clean machinery look.

The black oxide finish on these M6-1 x 45mm screws is uniform and slick, and the hex socket drive grips the Allen key without any slipping. Threaded portion is clean and cuts smoothly into aluminum. Pack of 400 will last me years of fixture building.

I needed some precise fasteners for a jig I'm building, and these M6-1 x 45mm screws fit the hex socket drive perfectly. The partially threaded design holds tight without stripping, and the black oxide gives them a nice, durable look.
