1/4-20 x 1/8 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.
Typical uses include pulleys and collars on light shafting, replacement knobs, and serviceable handles, where the exact diameter and length help match a tapped hole or service record. A straight slot transmits less seating torque than a hex socket; when maximum tightening torque governs, compare alloy steel socket cup point set screws. Compare Cup Point Alloy Steel Socket Set Screws when socket-drive tightening is preferred. Need these slotted sets in stainless? Ask; non-catalog sourcing is what Cold Headers does.
