1/4-20 x 1 1/2 Cup Point Slotted Headless Set Screw is sized for assemblies that need a cup point slotted headless set screw with clear thread and length identification. 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.

For collars, hubs, small gears, light shafts, and hardware where the set screw sits below the surface, verify the thread, length, and mating surface before substituting another set screw style.

Cold Headers is a Chicago specialty fastener distributor focused on practical replacement and sourcing support. Confirm the exact thread size and length, especially on legacy equipment where near-size substitutions can cause service problems.
