Locking Pliers are widely regarded as some of the most useful and versatile hand tools available. In this article we will look at some everyday practical uses for locking pliers which have resulted in them becoming an essential component in the professional tool kit alike.
Locking Pliers – how they work
If you’ve never used a pair of locking pliers before, they all operate on the same basic principle: a screw at the back of the tool is used to adjust the spacing of the jaws, and it usually takes a few seconds of trial and error to achieve the required setting for whatever object you want the pliers to grip. When the optimum setting has been dialed in, the jaws will close together with an audible “click”, and lock in place. Once locked in place, the pliers literally grip material like a vice; to release the jaws, there is a separate lever built into the handle which instantly disengages them when it is pressed.
Locking Pliers – uses
Locking pliers are something of a unique tool, being derived from both vices and pliers , they can be used for many applications that either clamps or pliers would be used for, as well as numerous other applications that hardly any other tool would be suitable for. Let’s take a look at some of the most common uses.
1. Clamping
The locking vice grip that is characteristic of these tools makes them a go-to solution for many clamping applications; some locking pliers are designed exclusively for clamping purposes, but all variants are suitable for this job. The heavy duty metal construction of locking pliers means they are especially favoured amongst welders, and it is common to find specialized locking pliers intended for the metalworking industry.
2. Holding
Locking pliers can be used to handle materials whenever it would be awkward or uncomfortable to grip them directly, for instance when working with heat or maneuvering small components into position for gluing or soldering. Long nose locking pliers are some of the most common tools for precision applications, and their tapered jaws enable the user to access more cramped workspaces and recessed areas.
3. Pulling Nails, Staples & other Fasteners
Because they clamp down on objects with considerable force, locking pliers can be used to extract stubborn nails and other fasteners where many standard pliers would struggle to provide sufficient hold under pressure. They are especially useful for extracting broken fasteners where there is no head to facilitate levering with a pry bar or claw hammer.
4. Extracting Rounded Nuts & Bolts
Similarly, if a nut or bolt has become sufficiently rounded that there is no chance of getting a spanner or socket to fit it, locking pliers can be used to grip the damaged part and turn the component in its threads, enabling the fastener to be removed (or tightened if necessary). If you are in a tight spot and there are no spanners or sockets available, locking pliers can also be used to drive undamaged nuts or bolts too. This can cause increased wear to fasteners so is not usually recommended except as a last resort; however some types of locking pliers have jaws which are designed with hex bolts in mind, and suitability can vary from model to model.
5. Replacing a Broken Knob or Lever
In the event that a knob, lever or other control handle is damaged or removed from a piece of apparatus, the operator is often faced with an unergonomic stub or shaft that can be difficult or impossible to turn by hand, especially if it is recessed or otherwise hard to access. Locking pliers make ideal replacement handles in these situations; once locked securely in place, they will generally enable sufficient turning or levering force to be applied to restore functionality until the component can be repaired or replaced.
6. Wire cutting
Though it is not a universal design feature, a great deal of locking pliers are built with an additional function built into the rear section of the jaws: an integrated wire cutter, which makes them a practical tool for snipping wire as well as bending, shaping and holding it. These cutters can also be used on pallet strapping, string, cable ties and various other materials.
7. Pinching off Pipes, Lines and Tubes
If you need to squeeze a tube or pipeline closed, e.g to suppress a leak or temporarily shut off a system for maintenance or repair, locking pliers make a quick and easy solution.
8. Driving screws
If you find you’ve broken or misplaced your trusty screwdriver handle in the middle of a job, locking pliers can be pressed into service as an emergency screwdriver bit holder. Simply lock the bit in place between the jaws and it will be held securely enough to apply ample torque for most light duty applications. It’s not the most ergonomic solution but it works well enough to finish off a half driven screw or remove a couple of fasteners in a hurry.
9. Light Duty Demolition and Shaping Tasks
If you need to bend or break materials like plastic and thin metals, locking pliers can be a useful piece of kit. The locking jaws do the gripping for you, enabling you to put more energy into twisting, levering and prying. Smaller long nose types are ideal for gripping material in awkward spaces, while larger models enable greater force to be applied for more heavy duty work. As well as greatly increasing the strength it would be possible to employ by hand alone, using pliers also ensures there is less risk of being injured by any sharp edges encountered in the process.
10. Pressing and Squeezing
Due to the force they are able to exert, locking pliers can also be used for fixing or assembling components like chain links and for crimping wire connectors.
Conclusion
There’s no doubt that locking pliers are just about the most versatile hand tools available and this article only covers a handful of typical everyday uses for them.
