The shortened pilot can help align or retain parts while reducing projection beyond the receiving hole, slot, or keyway.
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 5-40 x 1 1/2 include conveyor hardware, packaging machinery, and production equipment and shaft collars, gear hubs, and pulley positioning where the blunt pilot is part of the assembly fit.
