Selected for shaft-mounted and adjustment applications, 4-40 x 1/2 316 Stainless Steel Cup Point Socket Set Screw uses a cup point end form to concentrate contact at the screw tip.
Typical use cases include water-treatment equipment, outdoor machinery, and replacement assemblies, especially where 316 stainless is specified for more demanding exposure. 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, 1/2 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 cup point creates rim-focused contact that may help resist relative movement when the screw, mating material, and installation conditions are appropriate. Cold Headers supports exact-size sourcing for 316 stainless socket set screws, including uncommon lengths and replacement requirements.
