4-48 x 1 1/4 Cone Point Alloy Steel Socket Set Screw is selected for shaft-mounted parts that require a pointed set screw rather than a broad-ended contact.
Cone point geometry concentrates contact at the tip, so it is often seated into a pre-spotted or drilled dimple to control location and reduce wandering during service.
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 4-48 x 1 1/4 include couplings, handles, collars, and retained accessories and equipment rebuilds, service records, and exact-size substitutions where focused tip engagement is part of the assembly.
The 4-48 thread is UNF with 48 TPI, and the 1 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 assists with exact-size sourcing when cone point details matter to the final order.
