براغي رأس سداسي M12-1.75 × 210 مم | فولاذ فئة 10.9 عادي | ملولبة جزئياً (9 / عبوة)

Needed a strong bolt for a heavy machinery repair and these hex heads held up perfectly under full torque. The 210mm length with partial threads gave me just the right grip depth.

Installed these on a milling machine table and the class 10.9 steel handles the torque without any flex. The 210mm length is just right for bolting down thick fixtures, too.

These threads are solid – the 210mm length was exactly what I needed for a heavy jig I'm building, and the 10.9 grade gives me real peace of mind. They threaded clean into my steel brackets without any binding, and the hex heads took a socket wrench perfectly.
