5-40 x 1/2 Half Dog Point Alloy Steel Socket Set Screw suits compact machinery where a projected pilot is needed but extra length beyond the mating feature is not.

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 1/2 include maintenance bins, equipment rebuilds, and point-style controlled sourcing and couplings, handles, collars, and shaft-mounted accessories where the blunt pilot is part of the assembly fit.

Thread arithmetic for 5-40: 40 TPI in the UNC series; compare the 1/2 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 works with socket fastener requirements where pilot shape affects fit and ordering accuracy.
