4-48 x 5/16 Half Dog Point Alloy Steel Socket Set Screw gives a size-specific headless fastener for assemblies that use a shortened dog point as the locating feature.
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 4-48 x 5/16 include couplings, handles, collars, and shaft-mounted accessories and maintenance bins, equipment rebuilds, and point-style controlled sourcing where the blunt pilot is part of the assembly fit.
Thread arithmetic for 4-48: 48 TPI in the UNF series; compare the 5/16 in. length with tapped depth and pilot reach. For retrofit work, compare the end style against the original part before treating it as a generic set screw. Cold Headers assists with exact-size sourcing when the shortened pilot is part of the purchase requirement.
