Aircraft General Standards (AGS) were issued by the Directorate of Technical Development of the Air Ministry from the 1920’s and persist till today through substitutions to British Standards and AGS revisions. They relate to fasteners  such as bolts, nuts, rivets, fork joints, taper pins, common to all types of aircraft. AGS fasteners are made in a range of sizes and different materials.

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

 A. Raymond Tinnerman® & Palnut® (aka PAL) of Tinnerman Palnut Engineered Products, Inc. are leading brands in specialty clip-type fasteners including the world's largest selection of spring steel, stainless steel, and plastic engineered fasteners. Their fasteners replace traditional fastening methods with innovative solutions combining aesthetics and functionality. They are quick and easy to install, and do not require mounting tools.

Nuts and anchor nuts are extensively used fasteners in a wide range of applications in defence, aerospace, automotive, construction, and many other industries.They come in countless combinations of types, sizes, thread types, materials finishes & protective coatings and conforming standards.

Nylon locking nuts, also termed as stop nuts, nyloc, elastic stop, nylon-insert lock or polymer-insert lock nuts, are threaded hex nuts with a nylon insert, or collar, which is smaller than the thread diameter. As the nylon insert lock nut is tightened, the collar deforms over the mating screw/bolt threads, increasing friction on them, thus resisting vibration and loosening and maintaining reliable locking performance.These nuts are a preferred choice for equipment exposed to movement or vibration.
