براغي مقبس سداسي بنقطة كوب مع كرة نايلون #10-32 × 3/8 بوصة | فولاذ سبائكي (100/عبوة)

I needed set screws that wouldn't mar a shaft surface, and these nylon pellet tips did the trick perfectly. The cup point holds firm without damaging the material, and the hex drive allows precise adjustment even in tight spots.

The hex socket drive made tightening them in a tight spot on my setup effortless, and the cup point tip held the material perfectly without slipping. A solid pack for the price.

Used these for a jig fixture that sees moderate vibration, and the nylon pellet really holds its adjustment once torqued down. The hex socket drive lets me cinch them tight even in a recessed hole.
