5/16-18 x 7/16 Alloy Steel Cup Point Socket Set Screw is an Alloy Steel Cup Point Socket Set Screw used when a headless internal-hex fastener is specified for retaining or positioning a component.

In machine controls, collars, and retention work, this screw is often selected where a cup point is appropriate for localized holding contact. 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, and whether localized point contact is acceptable. This 5/16-18 x 7/16 size gives buyers a precise callout for ordering. Always confirm that the cup point contact is acceptable for the mating component and service conditions. The cup point creates rim-focused contact that can help resist relative movement when the screw, mating material, and installation conditions are appropriate. Cold Headers supports exact-size sourcing for socket set screws, including short runs, uncommon lengths, and replacement requirements.
