براغي رأس مقبس M5-0.8 × 22 مم | رأس زر بمحرك سداسي داخلي | ملولبة بالكامل | فئة 12.9 من سبائك الصلب بأكسيد أسود حراري (400 / عبوة)

I needed high-strength fasteners for building a workbench jig, and these class 12.9 alloy steel screws are seriously tough. The hex socket drive fits snugly and the threads are clean all the way down.

The hex drive on these M5 screws grabbed my Allen key perfectly without any slipping, and all 400 pieces came uniformly threaded. I used them to rebuild a jig at work, and they hold tight even under vibration—no complaints.

Finally found some M5 button head screws with a proper hex socket drive that don't strip out on me. The 12.9 alloy steel feels rock solid, and the black oxide finish held up perfectly during a tight jig assembly I was working on. These are exactly what I needed for my tooling projects.
