4-40 x 5/16 316 Stainless Steel Cup Point Socket Set Screw is commonly specified where a component must be secured from within a tapped hole rather than with an external screw head.
Applications often include instrumentation, fixtures, and adjustment assemblies, where compact internal-hex access is useful during setup. 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 before ordering. Confirm that point contact, 316 material, and service conditions fit the application. Final material selection should reflect chemical exposure, temperature, load, mating material, and service environment. This point style is intended for applications where localized contact is part of the retaining method, not for assemblies that require a nonmarking tip. Cold Headers helps match set screw thread, length, point style, material, and socket drive details for industrial purchasing and repair work.
