5/8-18 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 5/8-18 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 5/8-18 thread is UNF with 18 TPI, and the 1 1/4 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.
