[Technical Information] Basic Knowledge of Understanding Looseness: What is Torque and Axial Force Management?
How to determine the tightening torque necessary to manage the appropriate axial force! Introducing a simple calculation formula.
When fixing the joined components, the types of fastening screws include bolts and nuts. Axial force refers to the force that occurs when a bolt is tightened; the bolt tightening area is pulled in the axial direction and stretches very slightly. The reactive force that tries to return it to its original state is the axial force. If the axial force is not within the appropriate range, it can cause loosening or lead to the destruction of the joined components, making daily management of proper tightening torque and axial force important. Now, to determine the necessary tightening torque for managing the appropriate axial force, it can be calculated using a simple formula. We provide detailed information on this topic on our technical information site, "Screw Fastening Technology Navigation," which contributes to solving screw fastening challenges.

Company information
Hard Rock Industries is a company that develops, produces, and sells "locking nuts," and it was established in 1974. Our Hard Rock Nuts were created from the strong desire of our founder and technical president, Katsuhiko Wakabayashi, to eliminate accidents caused by loosening screws and to create a safe and secure society. We are still advancing the development and improvement of new anti-loosening products. Our products are used in critical safety locations and areas where maintenance and inspection are challenging. <Main Clients> Railway market (vehicles, tracks, overhead lines, etc.), bridges and highways, transmission towers, construction and civil engineering, plant equipment, industrial machinery, etc.
