1/4-20 x 3/16 Half Dog Point Alloy Steel Socket Set Screw is used where the blunt cylindrical pilot must enter a mating hole, slot, or keyway without a sharp point cutting into the surface.
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 1/4-20 x 3/16 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.
Thread arithmetic for 1/4-20: 20 TPI in the UNC series; compare the 3/16 in. length with tapped depth and pilot reach. Review whether the mating hole, slot, or keyway matches the point style before approving a substitute. Cold Headers works with socket fastener requirements where pilot shape affects fit and ordering accuracy.
