1/4-20 x 5/8 Cup Point Slotted Headless Set Screw combines headless installation with a cup point and straight slot for compact retention in light mechanical assemblies. For field service, the slot makes tool matching simple while preserving the compact installation expected from a set screw. Cup point geometry is a general-purpose set screw point for friction holding without requiring a drilled hole or machined flat.

It is a practical match for maintenance bins, repair kits, coupling collars, and non-critical retaining locations, with the cup point providing localized contact on the retained component. 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.
