براغي تثبيت سوكيت نقطة كوب مقاس 7/16-20 × 1-1/4 بوصة | فولاذ سبائكي (100/عبوة)

I've been using these set screws for a custom fixture, and the cup point really digs into the shaft without slipping. The hex socket makes it easy to apply the torque I need in tight spots.

Wanted these for a jig I'm building that needed a strong hold in a tight spot; the hex socket drive made installation straightforward even with limited clearance. All one hundred screws are consistent, and the alloy steel feels tough enough to handle the torque.

I was worried about stripping the hex socket during a tight install, but the cup point held firm and the drive engaged perfectly. Exactly what I needed for a machinery alignment job.
