براغي ذات رأس مقبس M24-3 X 90mm | محرك مقبس سداسي | ملولبة جزئياً | فئة 12.9 سبيكة فولاذ مطلية بالزنك (10 / عبوة)

I used these M24-3 x 90mm screws to secure a heavy jig, and the 12.9 alloy steel feels incredibly solid under load. The zinc plating seems to resist nicks well during tightening.

Pulled these out of the package and was immediately impressed by the clean zinc coating and the solid feel of the Class 12.9 alloy steel. They threaded perfectly into our press tooling with zero binding, and the 90mm length was exactly what I needed for the deep bore.

Installed these on a heavy jig fixture and the hex drive seated perfectly without stripping. The zinc plating looks clean and the partially threaded design gave me just the right grip depth for my setup.
