The metric all-metal dominant torque type hexagonal locknuts defined in the DIN 980 standard published by the German Standardization Institute (DIN) are also known as stove locknut, top locknut, crimped locknut, oval locknut. They are one-piece, all-metal dominant torque type hex locknuts with a tapered top with chamfered corners. Resistance to relaxation forces is created by deterioration in the upper teeth. These locknuts are considered unidirectional because they can only be installed one way. Because they are all metal, they are more resistant to higher temperatures and chemical exposure than non-metallic lock nuts (such as nylon snap lock nuts). They reach their dominant torque by breaking the threads of the nut, which then engages the mating part when tightened. Generally, these nuts are produced in various sizes and diameters ranging from M3 to M36.
Similarly, in the ISO 7042 standard published by the International Standards Organization (ISO), with threads M5 to M36 (inclusive), in product class A for threads up to (inclusive) M16 and in product class B for threads above M16 The characteristics of the prevailing torque type all-metal hex high nuts are described.
Similarly, in the ISO 10513 standard published by the International Standards Organization (ISO), the valid torque type in style 8 is all-metal hex nuts in product class A, nominal thread diameters from 36 mm to 2 mm, metric fine pitch thread. features are explained.
Our organization, among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, with its trained and expert staff and advanced technological equipment, within the scope of DIN 980 standard, for all metal dominant torque type hex lock nuts, within the scope of ISO 7042 standard. It also provides testing services for torque type all metal hex high nuts and applicable torque type all metal hex nuts within the scope of ISO 10513 standard.
