5-40 x 5/16 Oval Point Alloy Steel Socket Set Screw is used where a rounded oval point should bear against the mating surface without the cutting action of a cone or cup point.

Oval point geometry is useful when a shaft, groove, or angled surface must be repositioned during service without chewing the contact area.

Keep the alloy steel callout tied to the ordered part, while still reviewing exposure conditions and the surface condition expected at the contact point.

Typical review areas for 5-40 x 5/16 include adjustment screws, machine stops, and control knobs and conveyor equipment, packaging machinery, and production hardware where smoother point contact is part of the assembly.

The 5-40 callout corresponds to UNC thread form and 40 TPI; verify the 5/16 in. length against tapped depth and the desired bearing location. If a groove or curved seat is used, confirm that the screw reaches it without bottoming out in the tapped bore. Cold Headers assists with exact-size sourcing when oval point geometry matters to the final order.
