2-56 x 3/16 Knurled Point Alloy Steel Socket Set Screw is specified when the drawing calls for an alloy steel set screw with a knurled cup point and compact drive access.
The serrated knurled cup point bites the mating surface and helps resist vibration-driven back-out in blind holes, softer materials, collars, hubs, and adjustment locations.
Typical review points for 2-56 x 3/16 include automation equipment, fixture blocks, and serviceable machine covers; it may also fit gears, pulleys, sprockets, and adjustable stops where a headless set screw keeps the outside of the component clear while point contact provides the holding action.
The 2-56 thread designation identifies a UNC inch thread with 56 threads per inch, and the 3/16 in. length should be checked against tapped depth, contact location, and drive access.
The knurled cup point is usually chosen for localized bite rather than for a locating-hole function. Cold Headers helps maintenance and purchasing teams identify the requested set screw without turning it into a generic substitute.
