Designed for compact set-screw fastening, 4-48 x 5/16 Alloy Steel Cup Point Socket Set Screw combines Alloy Steel construction with a cup-shaped point for localized contact at the mating surface.

Typical use cases include conveyors, packaging machinery, and automation equipment, especially where maintenance teams need repeatable socket-drive installation. The internal hex drive keeps installation access compact while the headless body remains contained within the mating part.

For purchasing and replacement work, confirm the 4-48 thread, 5/16 in. length, socket size, and cup point diameter match the drawing or installed part. 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.
