Designed for use with United States Air Force visor-type Service Caps, also called “wheel caps,” these screw-in cap buttons feature the “wing and star” emblem that served as the insignia of the United States Army Air Corps, predecessor of the U.S. Army Air Forces that was transformed into the United States Air Force in 1947. When adjusting screw-in cap buttons, be sure to screw them in enough to ensure they’re secure and can’t come loose, but when the wings should be pointing to the sky when you’ve made any adjustments.
The original insignia used on Air Force buttons was the Seal of the Department of the Air Force, but in 1991 it was replaced with the legacy Army Air Corps’ emblem as part of the controversial “McPeak” Service Dress uniform. Although that uniform was ultimately discontinued in 1995, some of the ideas for its components, such as the “Hap Arnold button,” were incorporated into Air Force Uniform designs.
