براغي رأس مقبس M1.6-0.35 × 10 مم | محرك مقبس سداسي | ملولبة بالكامل | فولاذ سبائك فئة 12.9 أكسيد أسود حراري (600 / عبوة)

I needed tiny screws for a jig I’m building at work, and these fit perfectly without stripping the threads. The black oxide finish also gives them a clean, professional look.

The hex socket drive engaged perfectly with my tiny Allen key, making these precision screws a breeze to install in a tight jig. For such small fasteners, the 12.9 alloy steel feels remarkably sturdy and the threads are cleanly cut. Exactly what I needed for my machining project.

As someone who has struggled with cheap screws stripping under a hex key, these M1.6s hold their drive shape perfectly, and the black oxide finish has a nice, grippy texture. The 12.9 alloy steel feels seriously rigid for such a tiny fastener, and the threading is consistent across the whole 600-pie
