براغي تثبيت بمقبس نقطة كوب 1/2-20 × 1-1/4 بوصة | فولاذ سبائكي (100 / عبوة)

Bought these for a gear alignment job and the cup point bites into the shaft better than any other set screw I've used. The alloy steel feels tough and the 1/2-20 threads cut clean without galling. 100 in a box means I won't be running out anytime soon.

The hex drive really helps when you're working in a cramped spot—no slipping at all. These cup point screws held firm on a metal bracket I installed, and the alloy steel feels solid for the price.

These screws bit into the steel perfectly thanks to the cup point tip, holding firm even under heavy vibration. I appreciate having a full pack of 100 for future projects.
