12-28 x 1 1/4 18-8 Stainless Steel Cup Point Socket Set Screw is an 18-8 Stainless Steel Cup Point Socket Set Screw used when a headless internal-hex fastener is specified for retaining or positioning a component.
In tooling, fixtures, and adjustment assemblies, this screw is often selected where compact internal-hex access is useful during setup. 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 12-28 x 1 1/4 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.
