CHALLENGE
A customer was utilizing a standard mechanical click wrench in their process, which caused excessive scrap when used incorrectly. This type of mechanical click wrench is heavily dependent on the operator’s use and can allow the operator to apply additional torque/angle on the joint.
This ultimately affected the clamp load of the joint, causing stripped threads on the over-torqued applications. The customer was scrapping two to three castings per week due to stripped threads, at a cost of approximately $75 per casting.
