DIN 934, hexagonal nuts It is a standard published by the German Institute for Standardization (Deutsches Institut für Normung). This standard;
Nut dimensions (diameter, height),
Keyhole size,
Tooth form and tolerances determines all its technical specifications.
DIN 934 nuts are one of the most widely used nut types worldwide and ISO 4032 It is also largely compatible with the standard.
DIN 934 nuts are generally made of carbon steel (e.g. Class 4, 8, 10 strength), stainless steel (such as A2/304 and A4/316) and alloy steel. Material selection should be based on the conditions of the environment in which the bolt will be used (humidity, chemical exposure, temperature), as well as the required strength and corrosion resistance. Stainless steels are preferred in areas requiring corrosion resistance, while high-strength steels are preferred for connections under heavy loads.
Material selection, it should be made according to the application environment and the required mechanical properties. Commonly used materials are as follows:
Carbon steel: Class 4, 5, 6, 8, 10, 12 provides strength from low to high with such qualities.
Alloy steel: Systems operating under high temperature and pressure (e.g., with B7/B16 bolts).
Stainless steel: Offers high corrosion resistance with A2 (304) and A4 (316) grades.
Brass / Copper alloys: It is preferred in applications requiring electrical conductivity or for decorative purposes.
These nuts are used to join two or more parts together with metric threaded bolts or screws. Common applications:
Construction industrySteel construction and assembly systems
Automotive: Engine parts, chassis connections
Machinery and equipmentPump, valve, press, production lines
Power plants: Turbine, piping systems
White goods and furniture: Lightweight connections
Petrochemicals & shipping: Areas requiring high temperature and corrosion resistance
DIN 934 nuts can also be used in critical connections for structural safety. The correct thread type (coarse/fine), coating, and quality selection directly affect the safety of the application.
