DIN 6340 – Plain Washers for Bolted Connections

DIN 6340 defines plain washers designed for high-strength bolted connections, especially in precision engineering and mechanical applications. These washers are thicker and larger in diameter compared to standard washers, providing better load distribution and increased resistance to deformation. DIN 6340 washers are commonly used in applications where high-strength bolts, preloaded joints, and heavy-duty fastening are … Read more

DIN 6915 – High-Strength Hex Nuts for Structural Bolting

BSF – British Standard Fine Thread

DIN 6915 is a German standard that specifies high-strength hex nuts with large widths across flats, primarily used in structural steel connections. These nuts are designed to be used with DIN 6914 high-strength bolts and DIN 6916 washers to form preloaded bolted assemblies in steel structures such as bridges, buildings, and industrial frameworks.
