براغي ضبط رأس مقبس نقطة مخروطية محززة 3/8-16 × 1-1/4 بوصة | فولاذ سبائكي (100 / عبوة)

Needed a set screw for a stubborn pulley and the hex socket drive let me get a wrench in a tight spot—finally a perfect fit. The knurled cup point didn't mar the shaft either, which was a nice surprise.

The knurled cup point really grips the shaft—no slipping even after a full day of vibration on the machine. The alloy steel feels solid, and the hex socket made seating them in tight spots a breeze. Exactly what I needed for the job.

The hex socket drive made tightening these in a cramped machine compartment so much easier than using a standard wrench. I used a dozen on a fixture build and every one seated firmly without stripping.
