Here is what you need to know about safety wire pliers. A guide for auto enthusiasts and professional mechanics alike.
Safety wire pliers originated from the aviation industry, where they used them to hold bolts tightly. You tightly wrapped the safety wire end around the bolt to prevent it from loosening. Nowadays, they have also found a home within motorsport. This technique is not familiar. It’s only used where high-speed travel puts an additional strain on bolts.
Safety wire pliers are an excellent tool for any backyard mechanic or professional auto technician to have on hand. You can use these pliers to install and remove safety wiring, which is essential to prevent the nuts from loosening when they become vibrated by engine movement.
The chances are (because you’re reading this) you need a safety wire plier but are unfamiliar with what they are, how they work, and your buying options.
Safety wire pliers should not be confused with regular needle-nose or groove joint pliers, as their jaw shape is designed specifically for this task. We have reviewed five of the best models available so you can choose the right set for your needs!
What are Safety Wire Pliers?
A safety wire plier is a positive locking device that prevents fasteners from untightening and, eventually, coming out due to vibration and other forces. Safety wire pliers are put on the fastener, which is then pulled to tighten. Safety wire pliers come in various sizes and shapes, making it easier for you to work with different-sized wires. You can use safety wire pliers around any machine or other moving component where there may be a risk of the fasteners loosening due to forces and vibrations.
