Aircraft Tool Supply Safety Lock Wire (.032)

Safety wire is a metal cable with loops at each end. It’s used to tie down bolts on machinery, aircraft, and more. Safety wires are made from a durable material that will not break or give way when tension is applied to them, making them easy to use and reliable.

You can find safety cable in any industry where there is a need to prevent a bolt from becoming loose under heavy vibration. In particular, it is used in aircraft maintenance and even the space program! Let’s take a closer look at how this simple tool can make life easier in all of these areas.


Uses of Safety Wire

Safety wire is a cost-effective and efficient way to keep machinery and components secure. This includes bolt heads, self locking nuts, fasteners, and all other metal parts of machinery. This helps prevent accidents and injuries and saves companies the time they would otherwise spend finding and securing loose bolts or repairing equipment.

Safety wiring is not meant to replace bolts and fasteners installation. Always make sure that they are correctly tightened before installing safety cables with a torque wrench or other tool first.

Most manufacturers work very hard to ensure that their products are safe and reliable. One of the critical aspects in ensuring safety is securing all components that can work loose, such as those found on a motor or onboard aircraft. Safety wires should be tight but not too tight, with about 6-8 twists per inch for optimal security against breakage under pressure from vibrations like when an engine starts up – which can happen at any time!

Safety wire is a single-use, disposable item that you must replace after each use.
