براغي رأس مقبس M4-0.7 X 16mm | رأس منخفض، محرك مقبس سداسي | ملولبة بالكامل | سبيكة فولاذ فئة 10.9، أكسيد أسود حراري (400/عبوة)

Installing these into jig fixtures was a breeze thanks to the low head profile, and the Class 10.9 alloy gives me confidence they’ll hold up under repeated use. The 400-pack is a solid value for precision assemblies.

The black oxide finish on these M4 screws looks great and seems durable, and the hex socket drive fits my Allen wrench perfectly without stripping. I used them to rebuild a small jig for my drill press and they held tight under vibration. Exactly what I needed for precision assemblies.

I needed some low-profile cap screws for a tight jig assembly, and these 16mm fully threaded ones seated perfectly without binding. The hex socket drive gripped firmly at high torque, which saved me from stripping any heads during installation.
