In order to that it is possible to calculate connections with lockbolt systems according to VDI 2230 - Part 1. For the calcula-tion of lockbolt systems in mechanical joined connections the Technical Bulletin DVS-EFB 3435-2 is available for the design and calculation engineers. Furthermore savings in manufacturing and assembly as well as reduction of costs for expenses and maintenance are possible. These include the reduction of the required nominal diameter and consequently the reduction of component dimensions. Consequently cost can be safe because of the adjustments in mechanical engineering. In consequence of the advantageous notch effect because of a softer groove geometry, the larger stress cross section with the same nominal diameter and a lower scattering of preload the potential for increasing the load capacity of lockbolt systems in mechanical joined connections comes up in comparison to conventional screw connections. ![]() Lockbolts become increasingly important for modern mechanical engineering.
