براغي رأس سداسي M12-1.25 × 55mm | فولاذ فئة 10.9 عادي | ملولبة جزئياً (50 / عبوة)

These bolts handled the torque on my press brake fixture without any stripping, and the Class 10.9 steel gives me confidence they won't snap under heavy load. The partial threading made assembly quicker since I didn't have to chase threads on the whole shaft.

I needed a stronger bolt for a shop press rebuild, and the 55mm length and partial threading worked perfectly for clamping the die plate. The class 10.9 steel feels noticeably tougher than the hardware store stuff I've used before.

The hex head grabbed my socket wrench perfectly without any slipping, and the 10.9 steel feels solid enough for heavy equipment. Threaded portion is just right for a secure bite, arrived clean and ready to use.
