How do you select a precision torque wrench when comparing the technology and quality differences between a click wrench and a cam-over wrench? Each wrench mechanism design limits the amount of torque an operator applies. The type of torque limiting mechanism is what separates these wrenches in ensuring accuracy and precision.
Applying the correct torque to each fastener maximizes its holding potential. When too much torque is applied, it can strip or crimp threads, damage the fastener, or harm the assembly. Under-tightening can cause a screw or bolt to work free under stress, vibration, and fall out.
Click Wrenches
The most common type of torque wrench in the world, and the simplest, is the click wrench. Click wrenches are basic tools. 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 100 % process safe as the wrench is easily susceptible to torque failures and over-torque results. Often an operator misses the “click” sound nor feels the click movement because a click wrench does not physically prevent an operator from applying additional force. They unknowingly generate over-torque.
Cam-Over Wrenches
The poka-yoke wrench features cam-over technology and prevents over-torque. The wrench uses an internal cam-over mechanism to reduce the risk of operator error by disengaging once torque is achieved. Implementing this error-proofing wrench removes the operator’s influence on the torque equation and delivers an accurate and repeatable fastening result than a standard click-type wrench. You can provide a cam-over wrench to any operator and be confident that they will deliver the correct torque, time after time.
You can learn the benefits of upgrading from a click wrench to a cam-over torque wrench, which physically prevents its operator from applying too much torque from this webinar.
What You Will Learn:
- Why a click wrench cannot stop the operator from applying too much torque
- Ways to test and confirm a click wrench over tightened a fastener
- How cam-over technology prevents over-torque
- Understanding the quality and productivity benefits of implementing a preset cam-over wrench
- Making an error-proofing method seamless throughout the entire assembly process
- How to ensure correct torque is consistently applied.

Safeguarding against fastening failures requires you to deploy a torque wrench designed for error-proofing for the assembly process. Whether you’re in manufacturing or maintenance, the most important attributes your torque wrench should have are quality and reliability. And the best way to be sure the wrench you’re investing in will hold up on the line is to choose the right torque wrench technology.
Here’s your opportunity to learn how to make a business case for upgrading your click wrenches to cam-over wrenches.
