براغي رأس مقبس M6-1 × 16 مم | محرك سداسي | ملولبة بالكامل | فئة 8.8 سبيكة فولاذ مؤكسد أسود حراري (600/عبوة)

Installing these into some jig tooling and the 16mm length was exactly what I needed for a snug fit through a bracket. The black oxide finish seems durable enough to resist minor scratching during assembly, which is a plus.

The hex socket drive made tightening these into tight spots on my jig build much easier than using a hex key on a standard bolt. They threaded smoothly into pre-tapped holes without any binding. A solid choice for precision assembly work.

Just finished a tooling fixture and these M6-1 x 16mm screws held everything rock solid—the black oxide finish feels grippy in the hex socket, and the fully threaded shaft made alignment a breeze. Six hundred in the box means I won't be reordering for a while.
