براغي رأس أسطوانية سداسية M10-1.5 × 20 مم | رأس زرية بمحرك سداسي | ملولبة بالكامل | سبائك فولاذية فئة 12.9 مطلية بالزنك (100 / عبوة)

The hex socket drive seated perfectly on my Allen key with zero wobble, and the zinc plating looks clean and uniform across all 100 pieces. Threads were consistent too, no binding when I ran them into tapped holes for a tooling fixture.

Grabbed these for a jig I’m building, and the zinc plating looks even and the hex socket bites perfectly without stripping. Class 12.9 is the real deal for this price, and the full threading saved me from having to cut anything down.

The threading is clean and consistent across all 100 pieces, and the zinc plating gives them a uniform, professional finish. I've used about half of them for fixture assembly and haven't had a single one strip or bind.
