With its tried and tested functional features, Cetim Cobra can be used to calculate joint flexibility and stiffness, dynamic stress in threading, the minimum tension required to prevent breakaway, elongation after tightening (loosening), bearing stress in the different mating surfaces (contact deformation) and tightening conditions (torque, angle, tension). In addition to standards and codes such as VDI 2230 (1986), FDE 25-030, NFE 2503 Part 1 and ESA PSS.03.208, Cobra V6 now incorporates VDI 2230 (2003), novel technical devices like Nord-Lock washers and the latest recommendations from manufacturers.

The new V6 version includes many data entry wizards, bilingual (French-English) design notes, regularly updated standards databases on materials and fasteners, a conflict resolution wizard for differences in data entry, a built-in theory manual and 2D and 3D displays of joints. Used extensively in the fields of road, rail and air transport, its upgraded architecture means it can now be used for new developments, other applications and even other joining methods, such as bonding or riveting. Long established as standard design tool in various sectors of industry, Cetim Cobra has now become the must-have software in bolted joint optimization. With its open architecture (ideal for new developments), compliance with the VDI 2230 (2003) standard and data entry wizards in French and English, Cetim Cobra has undergone a transformation to stay ahead as the leading professional tool for optimising bolted joints. It's clearer, easier, more intuitive and, what's more, in 3D.
