براغي مقبس رأس أسطواني M5-0.8 × 45 مم | محرك سداسي رأس مسطح | ملولبة جزئياً | فولاذ سبائك فئة 10.9 أكسيد أسود حراري (400/عبوة)

These hold up great in my jigs—the partially threaded design seats perfectly and the black oxide finish hasn't shown a hint of rust after a week of shop use. The hex socket drive fits snugly, and for 400 pieces at this class 10.9 strength, the price feels almost unfair.

I'm rebuilding a tooling fixture and these 45mm M5 screws worked perfectly—the partially threaded design gave me just the right grip in the base plate. The black oxide coating handled my oily hands without any rust worry.

Had a jig that needed exactly these lengths and the partial thread gave just the right grip without bottoming out. The black oxide finish is a nice touch for corrosion resistance.
