5/8-18 x 2 1/4 Cone Point Alloy Steel Socket Set Screw is appropriate where axial and torsional holding depend on a pointed end biting into the mating surface.
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.
Use this material identity when the bill of material calls for alloy steel; environmental exposure and surface requirements should still be checked against the application.
Typical review areas for 5/8-18 x 2 1/4 include equipment rebuilds, service records, and exact-size substitutions and couplings, handles, collars, and retained accessories where focused tip engagement is part of the assembly.
The 5/8-18 thread is UNF with 18 TPI, and the 2 1/4 in. length should be compared with tapped depth and cone-point reach. Match the thread and length to the print because length changes can alter where the conical tip seats. Cold Headers works with socket fastener requirements where item-level details affect fit and ordering accuracy.
