The Purpose of Lockwire

What is Lock Wire? Lock wire is a crucial safety tool for ensuring mechanical stability. Bolts, screws, nuts, and other types of fasteners will gradually loosen over time, especially in applications that produce high levels of vibrations.

Applications like sports cars, aircraft turbine engines, and even weaponry can benefit greatly from the implementation of safety wire. Braking mechanisms, throttle systems, and even flight controls depend on lockwire to prevent serious mechanical failures and keep people safe, hence the name “safety wire.”

Lock wire’s central purpose is to prevent the loosening of nuts, bolts, and other fasteners. To wire lock nuts and bolts, you thread it through two or more fasteners, ensuring they remain as secure as possible. Safety wiring prevents the loosening of fasteners by counteracting it with more tightening. The common application method for the installation of safety wire involves twisting two strands of wire together with a “Double Twist” configuration.

However, it is important to avoid using safety tie wire for applications that involve excess chafing, tension, or fatigue outside of the wire’s intended tightening function.

Lock Wire Installation Methods

Performing safety wire installation involves choosing one of two methods: double-twist or single-wire.

For the double-twist application method, the diameter of the wire depends on the type of fasteners. Parts with hole diameters exceeding .045 inches require wiring of .032 inches in diameter. Those with hole diameters between .045 and .062 inches and spacing of fewer than 2 inches between each part require wire double-strand wire of .020 inches in diameter.

The single-wire or single-strand safety wire installation method is more applicable in situations with closely spaced fasteners such as electrical systems. The number of fasteners you can securely wire lock depends on how many are within reach of 24 inches of wire. The single-wire method also requires the use of the largest wire that can fit in the fastener’s hole.

Additionally, aluminum wire of .031 inch diameter, copper wire of .020 inch diameter, and similar types of wire function as seals on specific forms of equipment. This includes portable fire extinguishers, first-aid kits, emergency valves, and equipment with similar construction.

Tie Wire

Tie wire is incredibly useful for tying reinforcing. During construction, tie wire is an ideal choice for short durations. For extended periods of reinforcing, safety lock wire is the better choice.

Steel tie wire is among the most common types of tie wire. The process of making a tie wire reel involves annealing the wire. Annealing wire means to heat a wire to a certain temperature and then cool it at a certain rate. The desired result of annealing wire is to increase the ability of the wire to change shape with ease.

Tie wire is commonly used in construction and other industrial sites to reinforce steel bars and as reinforcing mesh. Tie wire also has a strong resistance to the elements. Tie wire uses are also prevalent in agriculture, packaging, and mining.

Malin has a wide variety of safety lock wire options, most notably stainless steel lock wire. Contact Malin today, for any tie wire, safety lock wire, or any of our other wire options.

Why is Safety Wire Used on Aircraft?

Keeping the Skies Safe

Safety wiring is used to secure components in aircraft to prevent sometimes fatal accidents. Also known as positive wire locking, safety wiring is a device that holds down parts such as nuts, bolt heads, screws, studs, and more.

Parts, such as screws, can become dislodged over time due to the vibration of the aircraft. In addition, even the smallest parts can create catastrophic results if not safety-wired and torqued into place. It is an important lesson for each aircraft maintenance technician to learn, as the safety of the passengers on an aircraft is the most crucial part of their job.

Wait… Aircraft Parts Can Fall Out?

Flight causes many stresses on an aircraft. For example, take-offs, landings, turbulence, and more constantly vibrate parts. Holding the aircraft together are many parts like screws, bolts, and other devices. Over time, these parts can become worn-down and sometimes become dislodged. Every single one of these components is important to the structure of the aircraft! Furthermore, just one loose screw can pose a problem for the safety of passengers and crew.

Additionally, to ensure that parts remain in place during all those stresses on aircraft, fail-safe devices, like safety wire, are installed. Aviation maintenance technicians are responsible for inspecting and ensuring that these parts and fail-safe devices, such as safety wire, are secure for each flight!

How Does Safety Wiring Work?

In aircraft, stainless steel wire is threaded through a hole drilled into a fastener or part, then twisted and anchored to a second fastener or part, then twisted again. With the tension of the wire, it remains in place by being twisted around itself. Additionally, the wire retains its shape after being bent to create a force against the loosening of fasteners such as screws.

Note that safety wire isn’t used just to be a replacement for tightening fasteners. Instead, think of safety wiring as a failsafe against the vibration of the aircraft. After each application, safety wire must be disposed of and replaced.

In addition, The most common sizes for safety wire are 0.032-inch and 0.041-inch, but wire also comes in various types for different jobs! For example, thicker wiring may be used to hold larger screws in place. Additionally, the wiring must be tight and even, but not under such tension that the wire is broken after normal handling or vibration.

Installing safety wire is something that should be practiced until it becomes second nature. Moreover, that’s why training is such an important factor in aviation maintenance!
