1/4-28 x 1 1/2 Cup Point Slotted Headless Set Screw gives maintenance teams a slotted headless set screw option with a cup point for general shaft and hub holding work. Because the screw has no head, it can thread below the surface of a collar, hub, knob, or housing when the tapped hole permits. The cup point is commonly used where localized holding contact is desired and the mating surface can tolerate set screw marks.

It is a practical match for fixture stops, knobs, handles, lever hardware, and small machine adjustments, with the cup point providing localized contact on the retained component.
