3/8-24 x 5/8 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 3/8-24 x 5/8 include handles, couplings, stops, and light indexing components; it may also fit production machinery that uses internal hex set screws to avoid external head clearance where a headless set screw keeps the outside of the component clear while point contact provides the holding action.
The 3/8-24 thread designation identifies a UNF inch thread with 24 threads per inch, and the 5/8 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 can quote this family by exact thread, length, alloy steel material, and knurled point style.
