What type of wrench is used to achieve snug-tight conditions on a nut for a substation structure?

The use of an ordinary spud wrench is essential for achieving snug-tight conditions on a nut in substation structures because it is specifically designed for the application of torque in settings where manual control is necessary. The spud wrench features a long handle that provides the leverage needed to apply sufficient force while allowing the user to feel the point at which the connection is snug-tight. This tactile feedback is critical to avoid over-tightening, which could lead to damage or failure in electrical connections or mechanical joints.

In the context of substation construction and maintenance, achieving the correct snug-tight condition is crucial for both safety and performance. A snug-tight condition means that the bolts and nuts are tightened just enough to eliminate any looseness without risking damage to the components or affecting their performance.

While other types of wrenches have their unique applications, they may not provide the same level of precision and control required for achieving snug-tight conditions effectively. For instance, an electric impact wrench may apply excessive torque, and a crescent or open-end wrench might not be able to offer the same leverage and feedback as a spud wrench. Therefore, selecting a spud wrench is integral to ensuring the integrity and reliability of the connections in substation structures.
