براغي رأس أسطوانية 1/4-20 × 3/4" | محرك سداسي منخفض الرأس | خيط كامل | فولاذ سبائكي معالج حراريًا أسود (300 / عبوة)

The low head profile on these screws was exactly what I needed to fit into a tight clearance on a fixturing plate. The black oxide finish seems durable and they threaded smoothly into tapped holes without any binding.

The low head profile on these screws made all the difference for a tight-clearance jig I was building. The black oxide finish looks great and seems to resist wear well.

I used these to replace some worn bolts on a jig in my shop, and the alloy steel with black oxide finish held up perfectly through a lot of tightening cycles. The hex socket drive gave a solid grip with my Allen key, and the 300-count pack means I have plenty left for future builds.
