| Description |
2-56 x 1/8 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 2-56 x 1/8 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 2-56: 56 TPI in the UNC series; compare the 1/8 in. length with tapped depth and pilot reach. Review whether the mating hole, slot, or keyway matches the point style before approving a substitute. If the design needs a longer pilot, compare this item with the full dog point family before ordering. Cold Headers assists with exact-size sourcing when the shortened pilot is part of the purchase requirement. Technical Highlights

2-56 x 3/16 Half Dog Point Alloy Steel Socket Set Screw identifies a half dog point set screw for alloy steel applications that need positive location and controlled protrusion. The shortened pilot can help align or retain parts while reducing projection beyond the receiving hole, slot, or keyway. 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 3/16 include fixture alignment, tooling plates, and locating slots and gear and pulley hubs that use a set screw pilot to hold position where the blunt pilot is part of the assembly fit. Thread arithmetic for 2-56: 56 TPI in the UNC series; compare the 3/16 in. length with tapped depth and pilot reach. Use the point style as a controlled specification, especially when replacing hardware from a prior drawing. For applications that require a deeper locating projection, the full dog point family may be the better comparison. Cold Headers has supplied specialty socket fasteners since 1962, including unusual locating set screw configurations. Technical Highlights

2-56 x 1/4 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. 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. 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 2-56 x 1/4 include keyways, mating holes, and retained adjustment points and keyways, mating holes, and retained adjustment points where the blunt pilot is part of the assembly fit. Thread arithmetic for 2-56: 56 TPI in the UNC series; compare the 1/4 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. When the receiving feature expects a longer pilot, review the full dog point option instead of stretching this selection. Cold Headers helps buyers keep dog-point details attached to the size being quoted. Technical Highlights

2-56 x 5/16 Half Dog Point Alloy Steel Socket Set Screw supports drawings where the pilot end, not only the thread and length, controls how the set screw seats. 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 5/16 include machine controls, stops, and register features and brackets, stops, and parts with prepared receiving features where the blunt pilot is part of the assembly fit. Thread arithmetic for 2-56: 56 TPI in the UNC series; compare the 5/16 in. length with tapped depth and pilot reach. Confirm that the pilot can enter the feature without bottoming or shifting the retained part. Use half dog geometry for shorter pilot clearance; route full dog point requirements to that separate family. Cold Headers can quote this half dog family by thread, length, alloy steel material, and pilot style. Technical Highlights

2-56 x 3/8 Half Dog Point Alloy Steel Socket Set Screw is made for fixture, shaft, and collar locations that call for a flat-ended dog-style pilot. 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 2-56 x 3/8 include conveyor hardware, packaging machinery, and production equipment and shaft collars, gear hubs, and pulley positioning where the blunt pilot is part of the assembly fit. Thread arithmetic for 2-56: 56 TPI in the UNC 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. If the print calls for extended pilot engagement, verify whether a full dog point set screw is actually specified. Cold Headers works with socket fastener requirements where pilot shape affects fit and ordering accuracy. Technical Highlights
