5-40 x 1/8 Alloy Steel Cup Point Socket Set Screw is commonly specified where a component must be secured from within a tapped hole rather than with an external screw head.
Applications often include shaft collars, hubs, and machine controls, where a headless fastener must hold a component without external head clearance. The internal hex recess gives the installer controlled drive engagement while keeping the fastener profile inside the tapped component.
The verified dimensions below help engineering and purchasing teams compare the screw to the application before ordering. Always confirm that the cup point contact is acceptable for the mating component and service conditions. Buyers should review the shaft or component surface condition, drive access, and required holding action before selecting this point style. Cold Headers is a useful source when the part number, thread, point style, or length is difficult to locate through standard catalog channels.
