2-56 x 1 1/4 Half Dog Point Alloy Steel Socket Set Screw is intended for applications where the blunt pilot aligns the component without pointed surface penetration.
For alignment work, the mating feature should be checked so the dog point enters cleanly and does not bottom before the set screw is seated.
Alloy steel construction belongs with set screw requirements where the design depends on the specified material and dog-style pilot geometry.
Typical review areas for 2-56 x 1 1/4 include industrial assemblies that require a blunt locating end and industrial assemblies that require a blunt locating end where the blunt pilot is part of the assembly fit.
Thread arithmetic for 2-56: 56 TPI in the UNC series; compare the 1 1/4 in. length with tapped depth and pilot reach. Confirm that the pilot can enter the feature without bottoming or shifting the retained part. Cold Headers supports maintenance, distributor, and production requests where point geometry changes the ordered item.
