1/4-20 x 1 1/4 Cup Point Slotted Headless Set Screw supports headless set screw applications where the slot, not a hex recess, is the intended drive feature. The headless form keeps the fastener contained in the tapped component while the screwdriver slot remains the drive interface. The cup point uses a hollow rim for localized contact on the mating shaft or component surface.

For older machinery, replacement assemblies, equipment panels, and adjustment screws in tight locations, verify the thread, length, and mating surface before substituting another set screw style.

Use Cold Headers for specialty fastener support when maintenance records call for uncommon cup point slotted sizes. Review the tapped-hole depth, screwdriver clearance, and point contact requirements before replacing a different point style.
