1/4-28 x 3/8 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.
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 1/4-28 x 3/8 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.
Thread arithmetic for 1/4-28: 28 TPI in the UNF series; compare the 3/8 in. length with tapped depth and pilot reach. Verify drive access and component clearance so the screw can be seated without external wrench space. Cold Headers assists with exact-size sourcing when the shortened pilot is part of the purchase requirement.
