5/16-18 × 1/2" براغي رأس أسطوانية | محرك سداسي رأس منخفض | كامل الخيوط | سبيكة فولاذية مؤكسدة حرارياً سوداء (200 / عبوة)

I needed some reliable fasteners for a jig I was building, and these socket cap screws fit perfectly in tight spaces thanks to the low profile. The black oxide finish gives them a nice, consistent look, and all 200 pieces in the pack were cleanly threaded without any burrs.

The low head profile on these screws let me fasten a tight jig assembly where standard cap screws would have stuck out too far. The black oxide finish looks clean and seems durable for shop use.

I needed a solid batch for a jig I’ve been building, and these low head screws fit perfectly into tight spaces where a standard cap wouldn’t clear. The thermal black oxide finish feels durable and hasn’t shown any wear after a few dozen test cycles.
