High Strength DIN 603 Carriage bolt And Nut Grade 4.8/6.8/8.8

Short Description:

DIN (Deutsches Institut für Normung – German Institute for Standardization) standards are issued for a variety of components including industrial fasteners as Metric DIN 603 mushroom head square neck carriage bolts. The DIN standards remain common in Germany, Europe and globally even though the transition to ISO standards is taking place. DIN standards continue to be used for parts which do not have ISO equivalents or for which there is no need for standardization. The ISO equivalent for DIN 603 mushroom head square neck carriage bolts is ISO 8678.

Carriage bolts were developed for use through iron strengthening plates on either side of a wooden beam. It is commonplace though to use them into bare timber, the squared section giving enough grip to prevent rotation.
