3-48 x 5/8 Cone Point Alloy Steel Socket Set Screw is a headless internal-hex fastener for assemblies that rely on pointed contact at the end of the screw.

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 3-48 x 5/8 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 3-48 thread is UNC with 48 TPI, and the 5/8 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.
