براغي ذات نقطة مسطحة من الفولاذ السبائكي، مقاس 3/8-16 × 2-1/2 بوصة (100/عبوة)

These set screws are solid and the hex drive fits perfectly for tight adjustments. I needed the flat point for a stubborn pulley application, and they held firm with no slipping.

The hex drive bit seated perfectly on these, and the alloy steel took the torque without stripping. I used a pair to replace worn-out fasteners on a press fixture, and the flat point gave a solid hold without marring the surface.

I needed some long set screws for a jig I was building, and these alloy steel ones threaded in smoothly without binding. The flat point held the adjustment perfectly, and having a hundred in the pack means I won’t run out anytime soon.
