براغي مقبس M5-0.8 × 20 مم | رأس زر بمحرك سداسي | ملولبة بالكامل | فئة 12.9 فولاذ سبائكي مؤكسد أسود حراري (400 / عبوة)

I needed a batch of these for a jig I was making, and the hex socket drive made them easy to torque down precisely. The threads cut cleanly into the tapped hole without any binding.

I needed a bulk pack for jig assembly, and these M5 bolts came perfectly threaded with a consistent black oxide finish. The hex socket drive seated firmly in my driver with no slipping, and the 400-count box was exactly what I needed for a full day of fixturing.
