براغي رأس كبس M10-1.5 × 30 مم | محرك سداسي | رقعة نايلون | كاملة الخيوط | فولاذ سبيكة درجة 12.9 أسود حراري مؤكسد (300 / عبوة)

The nylon patch on these is a lifesaver—they hold firm under vibration on my milling fixture without needing threadlocker. Black oxide finish looks clean and the 12.9 hardness gives me confidence they won’t strip.

I needed a full pack for a jig I was building, and these M10-1.5 x 30mm screws were exactly the right length and thread pitch. The hex socket drive made installation smooth with no cam-outs, and the nylon patch saved me from having to use separate thread locker.

Bought a batch for some custom jig work and the black oxide finish held up well against minor abrasion during assembly. The hex socket drive engaged cleanly every time without stripping.
