3/8-16 x 1 1/4 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.

The format suits service parts, restoration hardware, light mechanical stops, and replacement set screw inventories when a slotted headless set screw is already shown on the drawing or parts list.

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.
