Designed for compact set-screw fastening, 4-40 x 3/16 316 Stainless Steel Cup Point Socket Set Screw combines 316 stainless steel construction with a cup-shaped point for localized contact at the mating surface.
Typical use cases include process equipment, pulleys, and sprockets, especially where localized contact helps position a component on a shaft. The internal hex drive keeps installation access compact while the headless body remains contained within the mating part.
For purchasing and replacement work, confirm the 4-40 thread, 3/16 in. length, socket size, and cup point diameter match the drawing or installed part. Confirm point contact, 316 material, and service conditions fit the application. Use 316 stainless where the assembly calls for this material because of exposure or process-equipment requirements. 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.
