For assemblies that call for a 316 stainless set screw by exact size, 1/2-13 x 1/2 316 Stainless Steel Cup Point Socket Set Screw identifies the required material, cup point geometry, thread, and length.

It is commonly used in water-treatment equipment, outdoor machinery, and replacement assemblies, where 316 stainless is specified for more demanding exposure. The internal hex drive allows socket-wrench access from the threaded hole, which is useful when surrounding components leave little room for external wrenching.

Review the 1/2-13 thread, 1/2 in. length, socket size, cup point diameter, mating surface, and exposure before specifying the item. Confirm that point contact, 316 material, and service conditions fit the application. 316 stainless steel is often selected for improved corrosion resistance where moisture, cleaning chemicals, or chloride exposure matter. Buyers should review the shaft or component surface condition, available drive access, environmental exposure, and required holding action before selecting this item. Cold Headers is a useful source when the part number, thread, point style, 316 material, or length is difficult to locate through standard catalog channels.
