براغي رأس مقبس M5-0.8 × 22 مم | محرك مقبس سداسي | ملولبة بالكامل | فولاذ سبائك فئة 8.8 مطلي بالزنك (600 / عبوة)

I needed a bulk set for some jig builds and these M5 socket cap screws threaded cleanly into every hole without binding. The hex drive seated perfectly with my standard 4mm bit, and the zinc plating looks consistent across all 600 pieces.

These have a nice clean finish on the threads, so they seat smoothly into blind holes without binding. I used a full hundred of them on a jig build and didn't have a single one strip or fail.

Finally, a box of M5 screws where the heads don't strip out on the first turn. The zinc plating on these is even and smooth, and all 600 pieces in the package were clean and threaded perfectly.
