DIN 936

DIN 936 is a standard published by the Deutsches Institut für Normung (DIN) that specifies the requirements for hexagon thin nuts with metric threads. These nuts have a thinner profile than regular hexagon nuts and are used in applications where a low profile is required.

The DIN 936 standard defines the dimensions and tolerances for hexagon thin nuts in metric thread sizes, including thread pitch, thread diameter, and overall dimensions. The standard also covers the material requirements, heat treatment, and testing methods used to evaluate the performance of these nuts.

Hexagon thin nuts produced according to DIN 936 have a thickness less than the nominal diameter of the bolt they are used with. These nuts are commonly used in applications where a low profile is required, such as in machinery, automotive, construction, and electrical applications.

Overall, DIN 936 is an important standard for manufacturers and engineers who work with hexagon thin nuts with metric threads. It helps ensure that these fasteners meet certain quality and performance standards, including strength, durability, and resistance to corrosion. The selection of the correct nut size and thread pitch is important to ensure proper fit and functionality of the fastener, and to prevent failures and malfunctions due to mismatched components or improper installation.

Uses of DIN 936

1. Machinery and equipment: DIN 936 hexagon thin nuts are commonly used in machinery and equipment assembly, where a low profile and limited space are important factors. This can include everything from large-scale manufacturing equipment to small-scale precision instruments.
2. Automotive applications: DIN 936 hexagon thin nuts are used in automotive applications, such as engine assembly and suspension systems, where a low profile and limited space are required. These nuts can be found in everything from passenger cars to heavy-duty trucks and buses.
3. Construction and building: DIN 936 hexagon thin nuts are used in the construction and building industries, such as in steel fabrication and structural engineering applications. This can include everything from large-scale bridges and high-rise buildings to smaller-scale residential construction projects.
4. Plumbing and piping: DIN 936 hexagon thin nuts are used to connect pipes and fittings in plumbing and piping systems, including everything from household plumbing to industrial-scale piping applications.
5. Electrical and electronic applications: DIN 936 hexagon thin nuts are used in electrical and electronic applications, such as in the assembly of control panels and other equipment. This can include everything from small-scale electronics to large-scale power distribution equipment.

Overall, the DIN 936 standard ensures that hexagon thin nuts meet certain quality and performance standards, making them suitable for use in a wide range of industries and applications where a low profile and limited space are important factors. The selection of the correct material and grade is important to ensure the proper functionality and performance of the fastener. It's recommended to consult the manufacturer's documentation or markings on the nut to determine the specific material and grade used.
