All Metal Hex Flange Nut( DIN 6927 )

Q1: What is DIN 6927?

A1: DIN 6927 specifies a Flanged, All-Metal Prevailing Torque Hex Lock Nut, commonly known as a Flanged Stover Nut. It is a single-component fastener that combines a hex nut with an integrated, non-serrated flange (acting as a built-in washer) and a deformed-thread locking mechanism. The locking action is achieved by a controlled deformation of the nut's upper threads, creating increased friction and a prevailing torque that resists loosening under vibration and dynamic loads. While the original DIN 6927 standard has been withdrawn, its specifications have been largely incorporated into the European standards EN 1664 (for standard thread) and EN 1667 (for fine thread).

Q2: What is the ISO equivalent of DIN 6927?

A2: There is no direct, single ISO standard that is a perfect equivalent for the combined flanged and prevailing torque features of DIN 6927. However, the prevailing torque (locking) function of the nut body is covered by ISO 7042 for all-metal prevailing torque nuts. The dimensional aspects of the flange and nut are addressed in regional standards like the European EN 1664/EN 1667 series, which supersede DIN 6927.
