1/4-28 x 7/8 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.
Use this configuration for electrical panel hardware, equipment covers, control handles, and field service replacement work when the job calls for a headless screw and flat-blade drive access. A straight slot transmits less seating torque than a hex socket; when maximum tightening torque governs, compare alloy steel socket cup point set screws. For stainless material requirements, review Cup Point 18-8 Stainless Socket Set Screws.
For odd lengths or older slotted hardware callouts, Cold Headers can help identify the closest catalog path. The dimensional reference is ASME B18.6.2, cited here only as the slotted headless set screw dimensional standard.
