5/16-18 x 2 1/4 Cone Point Alloy Steel Socket Set Screw supports compact machinery where the screw installs fully inside the tapped part.

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.

Alloy steel construction is appropriate where the product specification calls for this family and the cone point geometry matches the intended contact condition.

Typical review areas for 5/16-18 x 2 1/4 include shaft-mounted parts that need concentrated point contact and gears, pulleys, sprockets, and control knobs where focused tip engagement is part of the assembly.

The 5/16-18 thread is UNC with 18 TPI, and the 2 1/4 in. length should be compared with tapped depth and cone-point reach. Review the mating material, drilled contact location, and allowable surface mark before changing point style. Cold Headers can quote specialty set screws by exact thread, length, material, and point style.
