Selected for shaft-mounted and adjustment applications, 1/4-20 x 5/16 18-8 Stainless Steel Cup Point Socket Set Screw uses a cup point end form to concentrate contact at the screw tip.

Applications often include fixtures, production equipment, and retention work, where localized holding contact is acceptable for the mating surface. 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. Confirm that point contact, material, and service conditions fit the application. Final material choice should reflect load, environment, mating material, and maintenance needs. 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 stainless socket set screws, including uncommon lengths and replacement requirements.
