3/8-16 x 7/8 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. 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.
