1/4-20 x 7/8 Cup Point Slotted Headless Set Screw is a carbon steel slotted headless set screw for adjustments that need simple drive access and below-surface installation. Because the screw has no head, it can thread below the surface of a collar, hub, knob, or housing when the tapped hole permits. The cup point is commonly used where localized holding contact is desired and the mating surface can tolerate set screw marks.
Engineers and repair technicians may specify this size for fan hubs, light-duty pulleys, positioning collars, and screwdriver-accessible tapped holes when below-surface installation is required. 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.
