Pliers are not wrenches. Even though it is easier to grab a pair and grip that nut or bolt tight, they are not the way to go. Wrenches are the perfect tool for nuts and bolts. So, what do you use pliers for?

Pliers are designed for gripping objects or cutting by using leverage. They have different jaw configurations to turn, pull, crimp, or cut a variety of items. There are several type of pliers that perform different tasks. Some of the most common types are slip-joint, cutting, lineman's, needle nose, locking, self-adjusting, and tongue-and-groove.

Cutting

Cutting pliers are built with sharp cutting edges with some major shearing power. These pliers are designed to cut heavy gauge wire, nails, and bolts. Unlike other wire cutters, cutting pliers are tapered to reduce the sudden "snap" when cutting. And the handles increase the leverage needed to cut thicker gauges. Bypass Secateurs
Lineman's

Lineman's pliers, also known as electrician's pliers, have flat deeply toothed jaws and a side-cutting blade. These pliers are designed for cutting, holding, and twisting solid electrical wire. The lineman's pliers is also great for bending and shaping light sheet metal.

Needle-Nose

Needle-nose pliers, also known as long-nose pliers, have a long and narrow jaws. This makes them great for working in tight places. These are also useful for intricate work like making jewelry and electronics work. Many needle-nose pliers come with a side cutting edge for cutting wire with precision. Side Cut Pliers

Slip-Joint

Slip-joint pliers can be found in just about anyone's tool box. They are a versatile form of pliers that provide two jaw width positions. One position allows the jaws to close on each other; perfect for perfect for grabbing thin objects. The second position leaves a gap between jaws allowing for a larger jaw capacity. Slip-joint pliers can be used in a number of gripping operations including removing hose clamps, pulling wire, holding nuts and bolts secure. Slip Joint Pliers

Locking

Locking pliers are adjustable pliers that lock closed on an object like a vise. This allows for a hand to be freed-up instead of having to hold the pliers in place. Most locking pliers have an adjusting screw that changes the width of the jaw opening to size of the object. These pliers also come in various sizes with various jaw styles; such as curved, straight, and needle-nose.

Self-Adjusting

Self-adjusting pliers are great as general purpose pliers. This pliers as a cam-and-ratchet mechanism that allows the pliers to quickly adjust to an object as the handle is squeezed. This keeps the jaws parallel to the sides of the object allowing for sturdy and accurate fit with exceptional gripping power.

Tongue-and-Groove

Tongue-and-groove pliers are similar to self-adjusting pliers except for they need to be manually adjusted to the size of the object. The adjustment is done through a series of grooves or channels. These pliers come in multiple sizes with different jaw styles; such as straight, curved, and smooth. They are generally used in plumbing applications. Aviation Tin Snips
