براغي رأس مقبس M10-1.5 × 100mm | رأس زر محرك سداسي | ملولب بالكامل | فولاد سبائك كلاس 12.9 مطلي بالزنك (50/عبوة)

I’ve been using these for jig repairs and the 12.9 alloy steel holds up perfectly under heavy clamping loads. The hex drive seated cleanly without stripping, and the zinc coating seems nicely applied. Exactly what I needed for precision tooling.

Needed a set of high-strength bolts for a custom press jig I'm building, and these 12.9 alloy steel screws handled the torque without any deformation. The zinc plating looks clean and uniform across all 50 pieces.

The hex socket drive on these M10 bolts fits my hex keys perfectly, no wobble at all. Used them to secure a heavy workbench frame and they threaded in smooth without binding—solid hold for the price.
