براغي رأس كبس M6-1 × 10 مم | محرك سداسي منخفض الرأس | خيط كامل | فولاذ سبائكي فئة 10.9 مؤكسد أسود حراري (300 / عبوة)

I needed a batch of low-profile socket cap screws for a tight clearance fixture, and these 10.9 alloy steel ones fit perfectly without any thread binding. The black oxide finish feels durable and hasn't shown any wear after repeated use.

Used these to rebuild a jig at work and the low head profile saved me from having to redesign the whole thing. The hex socket drive seated nicely with no stripping, and all 300 pieces had clean threads right out of the bag.

The black oxide finish on these held up perfectly during assembly, no flaking or residue on my fingers. The low head profile was a lifesaver in a tight jig where standard caps wouldn't have cleared.
