10-32 x 3/8 Cup Point Slotted Headless Set Screw is a slotted headless set screw for field adjustments where a flat-blade screwdriver is easier to source than a matched hex key. The slot can be driven with common flat-blade tools, avoiding the need to identify and carry a separate key size. The hollow-rim point can bite into the mating surface, so selection should consider whether a witness mark is acceptable.
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.
Use Cold Headers for specialty fastener support when maintenance records call for uncommon cup point slotted sizes. Review the tapped-hole depth, screwdriver clearance, and point contact requirements before replacing a different point style.
