DIN 6914

DIN 6914 is a German Industrial Standard that specifies the requirements for high-strength hexagon head bolts with large widths across flats, thread lengths equal to the total bolt length, and thread pitch M12 to M36 for use in structural steelwork connections.

The bolts covered by DIN 6914 are commonly used in construction and civil engineering projects, where high-strength and reliable connections are required. The standard specifies the mechanical properties, dimensions, tolerances, marking, and testing requirements for these bolts.

The DIN 6914 standard is equivalent to ISO 7412 and ASTM A325, which are international standards for high-strength structural bolts.

Uses of DIN 6914

DIN 6914 specifies the requirements for high-strength hexagon head bolts with large widths across flats, typically used in structural steelwork connections. These bolts are designed to provide reliable and high-strength connections in applications such as:

1. Construction: DIN 6914 bolts are commonly used in the construction of buildings, bridges, and other structures where high-strength and reliable connections are essential.
2. Civil Engineering: DIN 6914 bolts are also used in civil engineering projects such as dams, power plants, and offshore structures where high-strength connections are necessary.
3. Manufacturing: DIN 6914 bolts are used in the manufature of heavy equipment and machinery that requires high-strength connections.
4. Transportation: DIN 6914 bolts are used in the transportation industry for the assembly of heavy-duty vehicles such as trucks, trailers, and railway cars.

In summary, DIN 6914 bolts are used in applications that require high-strength and reliable connections in structural steelwork. They are commonly used in the construction, civil engineering, manufacturing, and transportation industries.
