1/2-13 x 3 Cone Point Alloy Steel Socket Set Screw is a pointed socket set screw for mechanical assemblies that need focused contact at the screw tip.
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 1/2-13 x 3 include conveyor equipment, packaging machinery, and production hardware and shaft collars, stops, and hub-mounted components where focused tip engagement is part of the assembly.
The 1/2-13 thread is UNC with 13 TPI, and the 3 in. length should be compared with tapped depth and cone-point reach. If a dimple or spotted hole is used, confirm that the screw reaches it without bottoming out in the tapped bore. Cold Headers works with socket fastener requirements where item-level details affect fit and ordering accuracy.
