1/2-20 x 3 Knurled Point Alloy Steel Socket Set Screw helps keep replacement sourcing aligned with the print when the specified point is knurled, not flat or dog style.

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 1/2-20 x 3 include tooling details, clamp collars, and positioning hardware; it may also fit machine repairs, replacement assemblies, and point-style controlled maintenance work where a headless set screw keeps the outside of the component clear while point contact provides the holding action.

The 1/2-20 thread designation identifies a UNF inch thread with 20 threads per inch, and the 3 in. length should be checked against tapped depth, contact location, and drive access.

Review the mating material, surface condition, and allowable witness mark before substituting a different point style. Cold Headers supports industrial set screw sourcing when the point style is easy to overlook on the print.
