  • AN Fasteners – The “Army-Navy” specification was developed to standardize parts for use in military equipment during World War II. Although this standard was replaced by MS military fasteners in the 1950s, a few types of AN hardware are still used today.
  • MS Fasteners – The “Military Standard” came into use during the 1950s and mostly replaced AN hardware. Mil-spec bolts, mil-spec screws and other US military fasteners were designated with an MS until 1994.  Builders in the aerospace industry relied heavily on this standard and when it was cancelled, they had difficulty finding the MS fasteners they needed.  The void left by the cancellation of MS fasteners led to the proliferation of modern mil-spec hardware designations that are currently used as aerospace fasteners.  While most types of MS military fasteners are no longer in use, some can still be found today.
  • NAS Fasteners – “National Aerospace Standards” ensure that NAS screws and other components are highly precise and strong. While these parts were originally developed for use as military spec fasteners, many types were adopted for use as commercial fasteners as well.
