2-56 x 1 1/2 Half Dog Point Alloy Steel Socket Set Screw supports shaft-mounted components that use a dog-style tip to register position.
Because the tip is blunt and cylindrical, it can locate in a prepared hole or keyway without the surface penetration associated with cone or cup styles.
This family is suited to industrial mechanical assemblies where a steel half dog point screw is part of the locating method.
Typical review areas for 2-56 x 1 1/2 include shaft collars, gear hubs, and pulley positioning and conveyor hardware, packaging machinery, and production equipment where the blunt pilot is part of the assembly fit.
