For assemblies that call for a stainless set screw by exact size, 5-40 x 1/8 18-8 Stainless Steel Cup Point Socket Set Screw identifies the required 18-8 material, cup point geometry, thread, and length.

In instrumentation, enclosures, and replacement assemblies, this screw is often selected where 18-8 stainless is chosen for clean appearance and routine moisture exposure. The socket drive helps maintenance and assembly teams install or remove the fastener without needing side clearance around a head.

Selection should account for the mating material, available drive access, environmental exposure, and whether localized point contact is acceptable. This 5-40 x 1/8 size gives buyers a precise callout for ordering. It fits many indoor industrial, outdoor general-service, instrumentation, and routine-cleaning applications. The recessed end form is often chosen where a witness mark or indentation on the mating surface is acceptable for the holding method. Cold Headers has supplied specialty socket fasteners since 1962 and helps buyers identify difficult stainless set screw configurations.
