Screws and bolts are commonly used as structural and non-structural fastening materials in aerospace, military and a wide range of industrial applications. Although quite often these terms are used interchangeably, screws differ from bolts as they are generally made of lower strength materials.Screws can be installed with a loose fitting thread, and the head shapes are made to engage a screwdriver or wrench. Some screws have a clearly defined grip (unthreaded portion) while others are threaded along their entire length (fully threaded).

Different have been developed and are currently employed in the procurement of fasteners by the Armed Forces, national and international agencies and industrial companies around the world in their attempt for uniform quality by establishing baselines for fastener characteristics, manufacturing processes, terminology, and expectations.These Standards cover a variety of required information on fasteners like their physical characteristics, like their inch or metric dimensions/tolerances, their material composition and chemical properties, property test methods, procedural instructions for fas
