For assemblies that call for a stainless set screw by exact size, 1/2-20 x 1 1/4 18-8 Stainless Steel Cup Point Socket Set Screw identifies the required 18-8 material, cup point geometry, thread, and length.
It is commonly used in instrumentation, enclosures, and replacement assemblies, where 18-8 stainless is chosen for clean appearance and routine moisture exposure. The internal hex drive allows socket-wrench access from the top of the threaded hole, which is useful when surrounding components leave little room for external wrenching.
Review the 1/2-20 thread, 1 1/4 in. length, hex socket size, cup point diameter, and mating surface before specifying the item. Confirm that point contact, material, and service conditions fit the application. 18-8 stainless is selected for general corrosion resistance, clean appearance, and ordinary moisture exposure. 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.
