براغي رأس كبس M18-2.5 × 120 مم | محرك سداسي | ملولبة جزئيًا | فئة 12.9 من سبائك الصلب مع أكسيد أسود حراري (10 / عبوة)

I needed 120mm length for a custom fixture, and these screws fit perfectly with no threading issues. The black oxide finish looks nice and should hold up well in the shop.

The black oxide finish handled some cutting fluid splashes without a trace of rust, and the 12.9 alloy steel torqued down to spec without a hint of stripping. Threads chased clean into our fixture plate on the first pass. These are keeper fasteners for any precision job.

The thermal black oxide finish has a nice even look and held up perfectly during assembly of my jig. Threads cut clean into the fixture and the 12.9 alloy steel feels absolutely solid. Exactly the right length for a 120mm setup.
