What Is a Plier Wrench?
A plier wrench is a versatile tool designed for gripping and tightening bolts and nuts. It is similar to water pump pliers, which are primarily used for plumbing maintenance but offers easier adjustability in the opening width compared to a monkey wrench. Unlike standard wrenches, plier wrenches apply force on two surfaces, reducing the likelihood of damaging the corners of bolts or nuts due to their firm grip.
Uses of Plier Wrenches
Plier wrenches combine the gripping capability of pliers with the tightening functionality of monkey wrenches and standard wrenches. They feature an adjustable opening width like monkey wrenches, but their flat gripping surfaces allow for secure tightening of bolts and nuts without corner damage.
How to Select a Plier Wrench
When choosing a plier wrench, consider the following:
Grip Type
- Plastic Grips: Common and thin, suitable for detailed work due to easy fingertip handling.
- Comfort Grips: Made of two materials, usually red and blue, offering a softer touch for extended use. They are generally heavier than plastic grips.
Aperture Width
The aperture width of plier wrenches varies. A wider aperture can accommodate various nut sizes. While less expensive models tend to have narrower openings, a wide aperture is not always necessary for general use. However, for diverse applications like factory work, a plier wrench with a broader aperture is recommended.
