Tips for Using Pliers Safely and Effectively

Why should pliers not be used on a nut or bolt?

- Pliers should not be used on a nut or bolt because _____.

A. They can round off the edges and make it difficult to remove or tighten

Answer:

Pliers should not be used on a nut or bolt because they can round off the edges and make it difficult to remove or tighten.

Explanation: Pliers are versatile hand tools used for gripping, bending, and cutting various materials. However, using pliers on nuts or bolts, especially those with hexagonal or square heads, can lead to several issues:

Damage to Fasteners: Pliers do not provide a secure grip on fasteners like wrenches or sockets designed for the purpose. When force is applied using pliers, they can slip, causing the jaws to round off the edges of the nut or bolt. This can make it challenging to apply adequate torque for tightening or loosening, and it can also damage the threads.

Reduced Torque: Pliers lack the mechanical advantage provided by tools like wrenches and sockets, which have a specific shape to engage with fasteners effectively. When pliers are used, it's difficult to apply sufficient torque to tighten or loosen nuts and bolts properly.

Safety Concerns: Using pliers on nuts or bolts can be less safe, as they are more prone to slipping and causing injury to the user. Wrenches and sockets are designed to minimize the risk of slippage.

To work efficiently and safely with nuts and bolts, it's advisable to use the appropriate tools like wrenches, sockets, or adjustable wrenches. These tools provide a secure grip, prevent damage to fasteners, and allow for precise torque application. Using the right tool for the job not only makes the task easier but also ensures that fasteners remain in good condition for future use.
