Selected for shaft-mounted and adjustment applications, 3-56 x 1/4 Alloy Steel Cup Point Socket Set Screw uses a cup point end form to concentrate contact at the screw tip.
Applications often include replacement assemblies, hubs, and positioning components, where the drawing calls out an exact cup point set screw size. 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.
