The TNA® System

Torque + Angle  TNA® is the only fastening system that delivers both a quantifiable Snug Tight condition – ensuring every bolt in a connection meets a minimum requirement for tension – and the precise required angle for the perfect final pretension. No other system or method can match the TNA® Torque + Angle Fastening System for producing the highest level of accuracy and reliability in both the snug and final tensioning processes.
