براغي مقبس سيت بونت 5/16-24 × 2-1/2 بوصة مع نقطة كوب | فولاذ سبائكي (100/عبوة)

The hex socket drive made seating these in a tight spot a breeze, and the cup point grips the shaft firmly without any slip. All 100 arrived clean and consistent, no burrs or duds in the batch. Exactly what I needed for a stubborn pulley setup.

I needed a long set screw for a custom jig, and the 2-1/2" length with that cup point really bites into the shaft. All 100 arrived in good shape with clean threads.

The hex drive fit my wrench perfectly, letting me torque these down in a cramped spot where a regular screwdriver wouldn't work. The cup point grabbed the shaft securely without slipping. Very pleased with the consistent quality across all 100 pieces.
