M17/184-00001 is a self-locking aircraft fastener standard certificated for aerospace and defense use by the RSCC (formerly the Radio-Standard Corporation of Canada). It is designed to securely attach lightweight components to an aircraft structure. It is a two-piece, self-locking nut design that uses a nylon insert to create a mechanical lock, which is threaded onto a mating bolt. This fastener has a higher tensile strength and shear strength than other fasteners in its category, making it especially suitable for use in aerospace and defense applications. Additionally, its two-piece design helps make installation easier, even in tight spaces. The fastener is also Resistant to environmental and service conditions such as vibration, temperature extremes, corrosion, fluids, and shock loading.
