براغي رأس سداسية M12-1.5 × 140 مم | فولاذ درجة 8.8 عادي | ملولبة جزئيًا (25 / عبوة)

These bolts threaded smoothly into the frame jig I'm building with a standard 19mm socket. The 140mm length gave exactly the grip I needed for a 50mm stack-up, and the class 8.8 rating gives me confidence they'll hold up under heavy load.

The hex fit on these M12 bolts was spot on for my jig assembly, and the 140mm length gave me just enough thread for a thick nut plate. Solid 8.8 steel, no bending issues under moderate torque.

I needed some long partially threaded bolts for a jig I was building, and the 140mm length was exactly right. The class 8.8 steel feels solid, and they threaded into my tapped holes without any binding.
