Our 4BA nyloc nut is a self-locking fastener with a nylon ring insert at one end of a hexagonal body. The nylon deforms slightly when threaded, creating friction to prevent loosening due to vibration. Common names include nylock nut and prevailing torque nut. This 4BA nyloc nut conforms to British standard BS 57 with a bright zinc plated and clear passivation finish and is widely used in industries where vibration resistance is important, such as automotive and aerospace.
