When completing assemblies, it can feel instinctive to make the fastening as tight as possible. It’s a common misconception that over checking will make the joint more stable and secure, but the effects can be detrimental to the quality and safety of the finished product. Some operating procedures even request that the fastening is double tightened, once with a DC tool and then followed by a manual wrench, this is known as over checking.
Using transducerised tools is the most effective way to eliminate over checking, and therefore speed up your processes. These tools can help to reduce takt time by up to 43%, helping to streamline the entire production process, meet demand more effectively and improve overall efficiency.
So let’s discuss the impact of over checking, and how transducerised tools can overcome them.
It seems counterintuitive, but a tighter fastening isn’t more secure. Adding an over checking step will lead to over torquing, in which the bolt is stretched and the joint becomes weaker and more likely to fail during use. As well as affecting quality, over checking adds an additional step to your production process which increases takt times and production lead times.
Over checking typically occurs using a clutch or pulse tool to carry out the initial tightening process, then a manual wrench to do ‘one last pull’ on the joint to ensure it has reached the target torque. Using a manual torque wrench increases the accuracy of the fastening process, but this method is slow and onerous for the operator.
Implementing a solution that prevents over checking is crucial, and transducerised tools are an optimal way to achieve this. Transducerised tools combine the speed of a clutch tool with the accuracy of a manual torque wrench. These tools have a built-in transducer which increases accuracy to the target torque ensuring consistency and accuracy.
