For assemblies that call for a stainless set screw by exact size, 3-56 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 3-56 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 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.
