A missing FEM record is not evidence of failed validation. It means no approved product-level study is public on this page.

COMBINATION BOUNDARY

Review the complete bolted joint

DIN 6796 washers compensate settlement and help maintain preload in predominantly axial short bolted joints. They are not an independent safeguard against self-loosening under alternating transverse load. Tightening torque requires thread, friction and assembly-method inputs.
