3/8-16 x 5/8 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.
For older machinery, replacement assemblies, equipment panels, and adjustment screws in tight locations, verify the thread, length, and mating surface before substituting another set screw style. Compare Cup Point Alloy Steel Socket Set Screws when socket-drive tightening is preferred.
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.
