Do I really need to use a torque wrench?

The purpose of using a torque wrench is to apply the target load for a specific amount of stress on a gasket.  For any given combination of gasket, bolt and flange, a stress range will ensure that the gasket will seal while, at the same time, protecting from over tightening that may cause damage to one of these components. Failure to remain within this stress range may result in environmental concerns, safety issues and downtime that can be expensive and dangerous. Understanding the types of torque wrenches, their advantages and how to maintain them will help operators apply the correct stress to gaskets. Specific guidance on a torque wrench’s use can be found in ASME PCC-1-2013.
