براغي رأس مقبس M6-1 × 55 مم | محرك سداسي المقبس | خيط جزئي | فولاذ سبائكي فئة 8.8 مطلي بالزنك (200/عبوة)

The hex socket sat perfectly flush in my driver—no wobble, no stripped corners even after torquing a few down in a tight jig. The zinc plating’s holding up nicely so far, and the 55mm length gave just enough grip for my 12mm-thick bracket stack.

The hex socket drive seated my Allen key perfectly on every single screw, and the zinc plating looks clean and uniform across all 200 pieces. I’ve been using them for a jig assembly and they thread in smoothly without any binding.

I needed a batch of M6x55mm socket caps for a jig I'm building, and these fit perfectly with clean threads and consistent depth across all 200 pieces. The zinc plating is even and hasn't chipped during installation.
