Implementing a solution that prevents over-torque events is critical for engineers to reduce scrap rate costs. Applying the right amount of torque to each fastener maximizes its holding potential. Over-torquing a fastener generates risks of fastening failures and damaged products.
Applying too much force while tightening a fastener can result in over-stretching a bolt, stripping a screw, breaking a screw head, or damaging the threads. The cam-over wrench’s mechanism design limits the torque an operator applies. This type of torque limiting mechanism is what separates different torque wrench technology. Cam-over wrench technology safeguards against fastening failures and enhances the reliability of the fastening process.
Click Wrenches
The most common type of torque wrench in the world, and the simplest, is the click wrench. A click wrench typically deflects by 3° and emits an audible “click” sound when the predetermined torque amount is reached. The click mechanism is not a 100 % process safe as the wrench is easily susceptible to torque failures. Often an operator misses the “click” sound nor feels the click movement. A click wrench does not physically prevent an operator from applying additional force. Fastening bolts with a click wrench expose manufacturers to a quality risk. The tool does not physically prevent an operator from applying additional force and is easily susceptible to over-torque results.
Cam-Over Wrenches
Engineered with a cam-over technology, the poka-yoke wrench prevents over-torque. The cam-over tool uses clutch mechanisms that prevent the operator from applying too much torque to the fastener, preventing over-torque events, broken components, costly product returns, and safety risks. Implementing this error-proofing wrench removes the operator’s influence out of the torque equation and delivers an accurate and repeatable fastening result than a standard click type wrench.
