4-40 x 5/8 316 Stainless Steel Cup Point Socket Set Screw is a 316 Stainless Steel Cup Point Socket Set Screw used when a headless internal-hex fastener is specified for retaining or positioning a component.
In chemical-processing equipment, hubs, and collars, this screw is often selected where the drawing calls for a specific 316 cup point set screw. The socket drive helps maintenance and assembly teams install or remove the fastener without needing side clearance around a head.
Selection should account for mating material, drive access, chloride or chemical exposure, temperature, and whether localized point contact is acceptable. This 4-40 x 5/8 size gives buyers a precise callout for ordering. It can fit washdown equipment, outdoor machinery, instrumentation, water-treatment hardware, and process equipment when 316 is specified. The recessed end form is often chosen where a witness mark or indentation on the mating surface is acceptable for the holding method. Cold Headers has supplied specialty socket fasteners since 1962 and helps buyers identify difficult 316 stainless set screw configurations.
