6-40 x 1 1/4 Cone Point Alloy Steel Socket Set Screw is a pointed socket set screw for mechanical assemblies that need focused contact at the screw tip.

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 6-40 x 1 1/4 include shaft collars, stops, and hub-mounted components and conveyor equipment, packaging machinery, and production hardware where focused tip engagement is part of the assembly.

The 6-40 thread is UNF with 40 TPI, and the 1 1/4 in. length should be compared with tapped depth and cone-point reach. Check the length against tapped depth and point reach so the cone enters the intended contact area. Cold Headers assists with exact-size sourcing when cone point details matter to the final order.
