止付螺絲，10-32 x 1"，內六角平頭

These flat point set screws seated perfectly flush in my jig and held fast under vibration without marring the shaft. The hex socket drive made installation a breeze even in tight spots.

Used a handful of these to lock down a jig on my drill press table, and the socket drive made tightening them in tight spots much easier. They bite well without marring the surface, exactly what I needed.

The flat point seated perfectly against the shaft collar in my mill setup, and the 10-32 threads cut cleanly without any binding. It's the kind of small part you don't think about until it just works.
