5-40 x 7/16 Knurled Point Alloy Steel Socket Set Screw is chosen where serrations at the point help the screw hold position against a prepared or softer mating surface.
The serrated knurled cup point bites the mating surface and helps resist vibration-driven back-out in blind holes, softer materials, collars, hubs, and adjustment locations.
Typical review points for 5-40 x 7/16 include repair bins, equipment rebuilds, and exact-size set screw substitutions; it may also fit tooling details, clamp collars, and positioning hardware where a headless set screw keeps the outside of the component clear while point contact provides the holding action.
The 5-40 thread designation identifies a UNC inch thread with 40 threads per inch, and the 7/16 in. length should be checked against tapped depth, contact location, and drive access.
Use the listed thread and length with the existing drawing or service record so the set screw reaches the intended contact area. Cold Headers helps buyers keep specialty point geometry, exact size, and material together during quoting.
