8-32 x 1/8 Cup Point Slotted Headless Set Screw uses a straight slot drive so a flat-blade screwdriver can seat the cup point without matching an internal socket size. The straight slot is useful in service kits, older equipment, and awkward access points where a screwdriver reaches more naturally than a key. Standard cup proportions run roughly 0.55 to 0.62 of nominal thread diameter, which is why the exact thread size matters.

Maintenance teams often review this type for communication equipment, control hardware, bracket stops, and repair work around legacy slotted screws, where a screwdriver-accessible fastener keeps service simple. 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.

Cold Headers has supplied specialty fasteners since 1962 and supports hard-to-find slotted set screw sourcing. Selection should reflect the shaft surface, required holding action, access for a flat blade, and the original hardware callout.
