Charting Loads and Torques. Tabulating data from bolt-load calculations is an easy way to speed the design process. The sample chart shown here is based on static conditions, class 2A and 2B ...

These values break out to 10.9%, 36.3%, and 52.8%, respectively, of the total torque, confirming the commonly heard assertion that only 10 to 15% of the input torque goes toward stretching the bolt.
