براغي غطاء رأس سداسي M42-4.5 × 240 مم | فولاذ عادي من الفئة 10.9 | ملولب جزئيًا (1 / عبوة)

The hex head on this M42 bolt grips my socket wrench perfectly without any slipping. At 240mm, it's just the right length for the heavy equipment frame I'm assembling. Tough 10.9 steel that feels solid and reliable for the job.

Finally found a bolt that doesn't strip when torqued to spec—the hex head on this M42 cap screw gave my wrench a solid bite. Used it to fasten a heavy press frame and the partial threading held perfectly without any wobble.

The threads are cut clean and the hex head fits my socket wrench perfectly, so torquing these down on the machine frame was hassle-free. For a 240mm bolt this size, the class 10.9 steel feels seriously solid, and the partial threading gave me just the right grip length.
