2-56 x 7/8 Half Dog Point Alloy Steel Socket Set Screw is specified when the print calls for a half dog point rather than a cone, cup, or flat style.

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.

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 7/8 include gear and pulley hubs that use a set screw pilot to hold position and fixture alignment, tooling plates, and locating slots where the blunt pilot is part of the assembly fit.

Thread arithmetic for 2-56: 56 TPI in the UNC series; compare the 7/8 in. length with tapped depth and pilot reach. Use the point style as a controlled specification, especially when replacing hardware from a prior drawing. Cold Headers can quote this half dog family by thread, length, alloy steel material, and pilot style.
