3-48 x 5/16 Cone Point Alloy Steel Socket Set Screw is appropriate where axial and torsional holding depend on a pointed end biting into the mating surface.
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 3-48 x 5/16 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 3-48 thread is UNC with 48 TPI, and the 5/16 in. length should be compared with tapped depth and cone-point reach. For replacement work, keep the cone point callout intact before comparing this item to other set screw families. Cold Headers assists with exact-size sourcing when cone point details matter to the final order.
