Bolted connections with reduced shank, survey and installation

This product is regulated by the following standards:

DIN 2510-1

Standard DIN 2510-1

The Part 1 of the norm Din 2510 describes application and installation examples, studies on the measurement of the screw connections. Bolted connections with reduced shank according to this standard are preferably used where the conservation of the bias and the durability of screw connections are to be largely ensured under varying of the mechanical and thermal loads.
