براغي رأس مقبس M27-3 × 260 مم | محرك مقبس سداسي | خيط جزئي | سبيكة فولاذ من الفئة 12.9 أكسيد أسود حراري

The 12.9 alloy steel feels incredibly solid when torquing down, and the black oxide finish resisted oil and chips on our production fixture. These M27 screws machined perfectly into our tapped holes without any binding.

The black oxide finish on these M27 screws makes them stand out from standard hardware, and they threaded smoothly into my jig without any binding. For heavy-duty tooling setups, the partially threaded design gives just the right grip depth.

Had to torque these pretty hard and the hex socket didn't strip at all, which says a lot about the 12.9 alloy steel. The black oxide finish on M27-3 threads is a nice touch for staying clean in oily tooling setups.
