5/16-18 x 3/4 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.

The format suits knurled knobs, hand wheels, shaft collars, and access points where a screwdriver is easier than a key when a slotted headless set screw is already shown on the drawing or parts list. Review Knurled Point Alloy Steel Socket Set Screws when the application calls for a more aggressive vibration-grip point.

Cold Headers helps match exact sizes for legacy hardware, maintenance work, and distributor sourcing requests. When replacing a removed screw, compare thread, length, slot condition, and whether the cup point matches the original intent.
