5-40 x 3/8 Cone Point Alloy Steel Socket Set Screw gives a size-specific alloy steel option for shaft hardware that calls for a sharp cone point.
The pointed end can also serve as a pivot or hanger point where the design intentionally uses focused contact instead of a broad bearing surface.
Alloy steel construction is appropriate where the product specification calls for this family and the cone point geometry matches the intended contact condition.
Typical review areas for 5-40 x 3/8 include gears, pulleys, sprockets, and control knobs and shaft-mounted parts that need concentrated point contact where focused tip engagement is part of the assembly.
The 5-40 thread is UNC with 40 TPI, and the 3/8 in. length should be compared with tapped depth and cone-point reach. Review the mating material, drilled contact location, and allowable surface mark before changing point style. Cold Headers has supplied specialty socket fasteners since 1962 and supports unusual set screw configurations.
