Here are some key details outlined in the DIN 985 standard:
- Design: DIN 985 nuts have a hexagon shape, allowing them to be tightened or loosened using a standard wrench or socket. They feature an internal nylon insert that provides the self-locking mechanism.
- Dimensions: The standard specifies the dimensions for the width across flats (s), which refers to the distance across opposite flat sides of the nut, and the nut height (m), which is the overall height of the nut.
- Material: DIN 985 nuts are typically made from steel or stainless steel, although other materials may be used based on specific requirements or applications. The standard provides specifications for the material composition and mechanical properties of these nuts.
- Performance: The primary function of DIN 985 nuts is to prevent unintentional loosening of fasteners. The nylon insert creates friction between the nut and the mating fastener, offering resistance to vibration and maintaining a secure fastening.
