Let’s talk joints – safetycritical or quality ritical? c Common applications: Choose the right tightening strategy On truck and bus assembly lines it is important to decide which application will be a safety critical, a quality/function critical or non quality critical application. This is in order to select the correct tool and tightening strategy for the application. The tightening strategy guides the process of applying the right torque to the selected bolt to achieve the correct clamp force. A normal truck is assembled using some 4,000 screws. If a customer wants to save weight it is...
