Generally, fasteners are made of rigid materials as they are responsible for holding two or more objects together in one place. Nevertheless, there are various fasteners made from nylon that are available in the market, such as zip locks, screws, nuts, etc. They all have specific uses and are vital in various appliances. Nylon fasteners are considered the best choice in some instances due to their superior quality over conventional metal types. Therefore, they are used in many appliances as they are shockproof fasteners. 

Aircraft fasteners are incredibly important components of any machine, and helicopters are no different. The main rotor of main helicopters is held in place by a so-called “Jesus nut,” called such by flight crews because to lose it was to have the main rotor detach completely and come face to face with him. While some helicopters do not feature a Jesus nut, all of them require fasteners that are precisely secured to ensure safe and controlled flight operations. This is why precision torque tools are so critical for helicopter maintenance, as every single nut, bolt, and screw must be tightened to exact specifications. If left loose, one can come free and damage the engine, propeller blades, or other components while in flight. If tightened too far, they can stress the housings and cause them to crack from the pressures and vibrations of flight.

A new member has joined the PEM family of lock nuts known as Type SL. These steel self-clinching locknuts by Penn Enginering use the TRI-DENT locking system to keep mating screws from loosening due to forces such as vibration, heat cycling, and other disruptions. The lock nuts meet 3 cycle locking performance and lock to the threads of mating screws. Type SL locknuts can also have screws removed without damaging the locking threads.
