براغي رأس مقبس سداسي منخفض مقاس M4-0.7 × 25 مم | محرك مقبس سداسي منخفض الرأس | خيط جزئي | فولاذ سبائكي فئة 10.9 مؤكسد أسود حراري (400 / عبوة)

The low head profile makes a real difference in tight clearance setups where regular cap screws won't fit. These hex drivers engage cleanly, and the black oxide finish adds a nice touch of corrosion resistance. Good value for a full pack of 400 pieces.

Finally a batch of M4 low head screws that actually hold up under repeated clamping; the black oxide finish has survived several assembly cycles without any visible wear. They're a perfect fit for tight clearance spots in my tooling fixtures where a standard cap head would snag.

Used these for a jig fixture at work and the black oxide finish handled cutting fluid without a hint of rust. The low head design saved me from having to counterbore, which was a nice bonus.
