3/8-16 x 1/8 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.
Use this configuration for electrical panel hardware, equipment covers, control handles, and field service replacement work when the job calls for a headless screw and flat-blade drive access. A straight slot transmits less seating torque than a hex socket; when maximum tightening torque governs, compare alloy steel socket cup point set screws. Compare Cup Point Alloy Steel Socket Set Screws when socket-drive tightening is preferred. Need these slotted sets in stainless? Ask; non-catalog sourcing is what Cold Headers does.
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.
