براغي مقبس M16-2 × 130 مم | رأس مسطح محرك مقبس | ملولبة جزئياً | سبيكة فولاذ فئة 10.9 مؤكسد أسود حراري (25 / عبوة)

Installed these in a machining fixture yesterday and the flat head hex socket grabbed perfectly without stripping. The 130mm length gave just enough thread engagement for my application.

I needed heavy-duty bolts for a jig I was building, and these M16s threaded in smoothly with no binding. The black oxide finish looks solid and should resist rust well in my shop. Great value for the price per pack.

The hex socket drive seated cleanly on my driver with zero wobble, and the black oxide finish wiped down easily after a day of assembly work. Threads ran smooth through the fixture, and the 10.9 hardness gave me confidence tightening them to spec without fear of stripping.
