The DIN 6925 standard published by the German Standardization Institute (DIN) describes the requirements for hex nuts, all-metal nuts with clamping piece.

In the standard in question, the requirements for hexagonal nuts and all-metal nuts with clamping parts are listed under the following headings:
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 describes the characteristics of the applicable torque type all metal hex high nuts (ISO 7042 Applicable torque type all metal hex high nuts - Feature classes 5, 8, 10 and 12).
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. (ISO 10513 Valid torque type all-metal hex nuts, style 2, metric fine pitch thread - Feature classes 8, 10 and 12).
Among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors, our organization, with its trained and expert staff and advanced technological equipment, within the scope of DIN 6925 standard, for hexagonal nuts, clamping piece and all-metal nuts, within the scope of ISO 7042 standard, It also provides testing services for valid torque type all metal hex high nuts and for valid torque type all metal hex nuts within the scope of ISO 10513 standard.
