For assemblies that call for an exact set screw size, 3-48 x 1/4 Alloy Steel Cup Point Socket Set Screw provides an Alloy Steel cup point design with internal hex drive access.
In replacement assemblies, hubs, and positioning components, this screw is often selected where the drawing calls out an exact cup point set screw size. 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 3-48 x 1/4 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.
