What are Locking Pliers?

Locking pliers have a unique design which allows them to be locked around whatever they’re holding. They can be easily adjusted to fit a variety of differently-sized objects.

All types of pliers are based on a lever and fulcrum system. Force is applied to an object for one of two purposes: To hold the object in place or move it in a specific direction.

Locking pliers use the same basic system as traditional pliers, but with extra features to securely grip objects. They’re also known as mole grip or vice grips, although “vice grips” are technically a brand name.

What are the Different Parts of Locking Pliers?

Jaws

The jaws are the front part of the pliers which grip and hold. Many different jaw shapes are available but curved and straight are the most common. Curved pliers are also called “lobster pliers.”

Teeth

The small, sharp ridges inside the jaws are the teeth. They hold onto the smooth surfaces to distribute pressure equally.

Handles

The handles should be easy to hold and comfortable. Most handles have rubber sleeves. For auto repair purposes, the handle should be easy to grip even when your hands are wet or covered in slick substances like oil or grease.

What are the Benefits of Locking Pliers?

Like traditional pliers, locking pliers are used to both tighten and remove objects. However, because locking pliers allow for a precise fit, they’re often the preferred tool when dealing with stubborn fasteners such as:

  • Stuck joints
  • Cross-threaded screws
  • Stuck nails

Locking pliers have several benefits over the traditional type:

Locking pliers require less physical strength to use compared to traditional pliers. With traditional pliers, the force applied comes from the hand strength of the person holding the pliers. However, locking pliers apply their own pressure, which allows for a grip tighter than what a person is capable of creating.

Locking pliers allow for single-handed operation. They can be adjusted, locked and released all using one hand. Keeping one hand free is especially useful when working underneath a car.

Finally, locking pliers are safer than traditional pliers. Once you lock an object in place, you can rest easy knowing it won’t move, turn or shift until you hit the release lever.

What Features Should Locking Pliers Have?

Locking pliers are relatively simple to use but have a rather complex construction. You’ll want to consider each of the following features:

Materials

The pliers should be well-made and strong. They need to hold their position regardless of the surrounding environmental conditions. Make sure they can withstand intense heat, which is frequently encountered when working on cars.

Choose locking pliers made from high-grade, forged steel. Heat-treated alloy steel is a popular and durable option. For additional protection, choose pliers with a rust-resistant coating.

Sharp Teeth

The strength and shape of the teeth directly affect how securely the pliers can grip and move objects. If the teeth are soft, the pliers will likely frequently slip. Choose a pair of pliers with hardened teeth. Additionally, small, sharp teeth will provide a fuller grip.

Adjustable Screw

The adjusting screw allows you to change the pressure based on the size of the object held. Most pliers place the adjusting screw in the handle where you can easily reach it with your thumb.

Check the size limits of the pliers. Your car has a variety of differently-sized components. For auto repair, you want locking pliers which can grip everything from small screws to large hoses.

Also, the pliers should be adjustable in small increments, so they’ll maintain a secure grip on a wide range of objects.

Release Lever

Release levers allow you to quickly remove the pliers without having to reach away from the handle. A release lever is the easiest way to unlock pliers when they’re locked in at an awkward position – and pretty much all auto repair involves holding tools at awkward positions!

One-touch levers are the best option. They’re not only easy to use, but they also reduce the risk of pinching.

Jaw Style

Locking pliers have a variety of nose and jaw styles. The two most common are curved and straight.

Curved pliers are the best option for loosening frozen nuts, bolts and screws. They’re also a good choice for any demolition.

Straight pliers are the better option for clamping smaller objects. Pliers with a long, thin nose allow you to reach tiny spaces deep inside the engine. Straight pliers are also an easy way to remove broken screws, pins or nails.

How Do I Use Locking Pliers?

Locking pliers aren’t particularly complicated to use, but there are a few techniques which can make them easier to work with. Here’s the most efficient and effective way to use locking pliers:

1. Open the Pliers

On the inside of the pliers, you’ll see a tab or lever. Pressing it separates the handles and jaws.

2. Fit the Pliers

Place the jaws around the object you want to hold, turn, move or otherwise engage.

3. Secure the Object

Squeeze the handles to close the jaws around the object. There’s no need to squeeze too hard. Let the pliers do most of the work. Once the pliers are generally in place, the fit can be finetuned by tightening the adjustment knob or screw.

4. Move or Hold the Object

Once the fit is secure, the object is held, and you can let go of the pliers. You can also twist or otherwise move the object.

5. Release the Object

Press the tab or move the lever on the inside of the handle to release the grip and free the object.

Do Locking Pliers Have Any Safety Risks?

Pliers are generally one of the safest tools available, as they have no electrical components and minimal sharp edges. However, there are a few potential dangers you can encounter.

The biggest potential hazard is skin pinching. It’s easy to accidentally catch a finger or hand webbing when you’re closing the plier. Even though this probably seems like no big deal, it can actually be pretty painful, especially if you cut your hand against the wire cutters.

The automotive repair involves working in small spaces with low-light conditions. You won’t always be able to see your hands when using pliers and other tools. Pliers with pinch guards help protect your hands from accidental injury.

Another common problem is when the held object slips from the grip of the pliers. Never use locking pliers to hold objects which are too small or too large for the jaws. Attempting to grip an object which is too small for the jaws can result in scratches to the object. Attempting to grip an object which is too large can cause the object to slip from the jaws suddenly.

Locking pliers between six and eight inches are usually the best size for general purpose automotive use. However, if you want the most flexibility when working on your car, choose a set of three or four differently-sized pliers.

Also, be aware of potential electrical hazards. The rubber grip on the handles is not an insulator. Electricity can easily travel through a pair of pliers. If you’re working on an electrical system in your car, be sure and first disconnect the battery.

How Do I Keep My Locking Pliers in Great Condition?

Water is a pair of pliers’ greatest enemy. Most will have a rust-resistant coating to protect against mild liquid exposure. Rust resistant coating is especially important when choosing pliers to use for automotive work. Water, coolant, oil and other liquids run through practically every system in a vehicle. Your pliers will be exposed to all sorts of fluids during normal maintenance procedures.

However, note that rust resistant doesn’t mean “completely waterproof.” You can’t keep your pliers submerged in any type of fluid for an extended period because they’ll rust. Never use rusted pliers. Rust degrades the structural integrity of the pliers, making them unsafe to use.

Of course, pliers aren’t allergic to water. After every use, wipe them clean with a damp sponge or cloth. Even just a small amount of coolant, oil, etc. can wear away the finish of your pliers. Keeping them clean helps prolong their life.

What Other Pliers Do I Need for Auto Maintenance?

Automotive tools are often highly specialized. While locking pliers are the best choice for clamping, they’re not the only pair of specialized pliers you’ll want in your garage. Here are a few other pliers which are frequently useful in auto repair:

Hose Grip Pliers

They’re mainly used for fuel lines, heater hoses and other engine hoses. Hose grip pliers have grabber jaws which won’t puncture flexible hose materials. These pliers are also often used to change spark plugs.

Brake Spring Pliers

Changing the springs inside your drum brakes? You’ll want Brake Spring Pliers. They have a round tip to remove old springs and a curved tip for installing new ones. While traditional pliers will also work for this type of job, these specialized pliers make the work much easier and faster.

Battery Pliers

Don’t change your car battery without a pair of Battery Pliers nearby. They have short, angled jaws specifically designed for car batteries and jumper cables. These pliers are thick, compact and durable. Note that Battery Pliers don’t necessarily insulate you from electric shock so be sure and take appropriate precautions before touching the battery.

Bent Nose Pliers

Bent Nose Pliers are perfect for reaching tight, awkward spots deep inside your engine. The jaws have either a 45 or 90-degree angle. They’re mainly used for moving wires and other electrical work. Much like Battery Pliers, Bent Nose Pliers won’t necessarily protect you from electric shock.

Slip Joint Pliers

These classic pliers have fallen out of favor with many mechanics, but they have a lot to offer. Slip joint pliers are highly versatile. They can hold components, twist fasteners, strip wires and more. They’re useful in the early stages of diagnosing a car problem. When you need to poke around the engine, bring a pair of slip joint pliers along with you.
