5-40 x 5/8 Oval Point Alloy Steel Socket Set Screw identifies the exact thread and length for an alloy steel oval point socket set screw.
Because the end is smooth and crowned, this style is often reviewed for adjustment screws, stops, knobs, and retained parts that move during setup.
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 5/8 include conveyor equipment, packaging machinery, and production hardware and adjustment screws, machine stops, and control knobs where smoother point contact is part of the assembly.
The 5-40 callout corresponds to UNC thread form and 40 TPI; verify the 5/8 in. length against tapped depth and the desired bearing location. Check the length against tapped depth and contact location so the rounded end reaches the intended seat. Cold Headers works with socket fastener requirements where contact shape affects fit and ordering accuracy.
