Click vs Cam-Over Wrench Technology



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.
Applying the right amount of 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 a 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 he/she unknowingly generating over-torque.

Cam-Over Wrenches
Engineered with a cam-over technology, the poka-yoke wrench prevents over-torque. The wrench uses an internal cam-over mechanism to reduce the risk of operator error by disengaging once torque is reached. 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. You can provide cam-over wrench to any operator and have the confidence that he/she will deliver the correct torque, time after time.

Safeguarding against fastening failures requires you to deploy a torque wrench designed error-proofing for the assembly process. Learn the quality benefits of upgrading from a click wrench to a cam-over torque wrench, which physically prevents its operator from applying too much torque. 

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.

Here’s your opportunity to learn how to make a business case for upgrading your click wrenches to cam-over wrenches.
