براغي رأس سداسي M30-3.5 × 220 مم | فئة 10.9 فولاذ عادي | جزئية الخيوط (2/عبوة)

The unthreaded shank on these M30s provides plenty of grip depth for my heavy press jig setup, and the 10.9 steel feels solidly hardened. They fit my socket perfectly without any slop. Exactly what I needed for industrial-grade assembly work.

The hex head on these M30 screws gives my wrench a solid grip even in tight spaces, and the 10.9 steel feels really tough for heavy machinery work.

The partially threaded section made alignment a breeze when I torqued these down to spec, and the hex head took a socket without any stripping. Class 10.9 hardness is exactly what I needed for this heavy-duty fixture.
