Meanwhile, extensive research and testing at GE Aircraft Engine facilities revealed that the use of Bergen Safety Cable instead of lockwire resulted in a 50 percent reduction in installation time with consistently superior quality and lower assembly costs.
In today’s manufacturing environment, speed and quality are everything. Here are a few reasons why Bergen Safety Cable is superior to lock wire.
When traditional lock wire is removed from an application, it needs to be cut many times in order to be completely removed. This process produces numerous small fragments which are difficult to keep track of. If the scrap material cannot be fully recovered, it can cause serious damage to the aircraft and potentially its passengers as well. This is known as foreign object damage or FOD. However, when Bergen Safety Cable is removed, it produces only two pieces of scrap, making it easy to keep track of and eliminates the potential for FOD.
The Bergen Safety Cable tool was designed specifically to allow access to restricted areas. The short length of the tool as well as the tool nose, which can be rotated 360 degrees, assists operators working in these tough conditions.
Using traditional lock wire requires that the operator determine how much wire to use, how many twists per inch, and many other important details. If a step is missed or completed incorrectly using lock wire, the operator must start all over. With Bergen’s Safety Cable system, all the guesswork is eliminated. The operator simply strings the cable through the fastener holes and the safety cable tool does the rest, which results in perfectly wired fasteners every time and increased production.
The cumbersome nature of applying traditional lock wire can take a very long time to master. With the streamlined method of the Bergen Safety Cable system, a new operator with zero experience can be up and running within 30 minutes.
Traditional lock wire produces very sharp ends when cut, which poses a serious threat of injury to the operator. The fused ends and flexible nature of Bergen Safety Cable removes the risk of injury 100 percent.
The Bergen Safety Cable tool was designed with the user in mind. Our tool utilizes the best principles of ergonomics, which allows the tool to fit comfortably in the operator’s hand.
Using the Bergen Safety Cable system simplifies the task of lock wiring fasteners together. The simplicity translates into time savings, which allows an operator to complete a job in half the time. The time savings allows the operator to move on to the next project faster, which can double production.
Other benefits include reduced inspection time, consistent cable tension on each application, and a material that is lighter than lock wire and traditional safety wire. Choosing to use Bergen Safety has a myriad of significant benefits that our customers agree improve product quality and save them time and money across the board.
Safety lock wire, also known as wire locking or safety wire, is a type of positive locking device that prevents fasteners from loosening or falling out due to vibration and other stresses.
The primary purpose of safety lock wire is to secure fasteners and other components, providing an added layer of safety and security in various industries, most notably in aerospace and defense.
The concept of safety lockwire dates back as early as the advent of aviation. Early aircraft were subjected to intense vibrations, which often caused fasteners to loosen, resulting in mechanical failures. To combat this, a safety lock wire was introduced.
Over the years, the use of safety wiring has extended beyond aerospace, finding its place in any application where safety and security are of utmost importance. Today, it continues to play an essential role in maintaining operational safety and efficiency, testifying to its enduring relevance in the mechanical world.
Whether you need aluminum wire, stainless steel wire, copper wire, or brass safety wire, knowing more about this topic is essential for you to make the right assessment and get the best products. Read on to find out everything.
Stainless steel lock wire is a popular choice when it comes to installing safety wire due to its high resistance to heat and corrosion. Made from 304 stainless steel, it’s famous for its tensile strength and its ability to perform under extreme conditions, making it perfect for use in industries such as aerospace and defense.
This safety wire is easy to work with, resists fraying, and holds its shape well. There will be variants on the results you get depending on whether you rely on a single-wire method, a double-wire method, and other electrical systems for you to get the results you want. However, it’s still one of the most popular alternatives.
Inconel Lockwire is known for its high temperature and corrosion resistance, making it an ideal choice for industries that work in more demanding environments.
It’s made from a family of superalloys composed of nickel and chromium and can retain its strength even when exposed to temperatures up to 2000°F. This type of lockwire is particularly beneficial in applications, such as fastening critical components in aircraft engines, where high heat is common.
Monel Lockwire is made from a series of nickel-copper alloys. Known for its excellent strength and corrosion resistance, particularly against seawater and acids, this type of lock wire is often used in marine and chemical applications.
Despite its strength, Monel Lockwire is also highly malleable, making it easier to secure fasteners in tight or awkward spaces.
The wire gauge and thickness of the safety wire are critical aspects of its performance and strength. With a diameter of 0.047 inches, this specific lockwire is designed to provide the right balance between flexibility and sturdiness.
The thickness allows the wire to be effectively threaded through fasteners, without compromising its resistance to stress or strain.
Thicker wires tend to have greater strength, but they may lack the flexibility needed for secure installation. Hence, selecting the right gauge and thickness is a defining factor for the effectiveness of the safety wire.
Safety lockwire works primarily through the application of tension and torque. Once threaded and twisted around the fasteners, the tension in the wire prevents the loosening of these components.
The wire is designed to maintain this tension, even under conditions of high vibration or sudden impact. Furthermore, the torque applied during the installation process ensures that the wire is tightly wound and secures the fasteners effectively.
However, it is crucial to consider the torque limit of the wire to avoid over-tightening, which could lead to the wire’s failure. Therefore, understanding and applying the correct tension and torque is key to maximizing the effectiveness of the safety lock wire.

The aviation industry heavily relies on safety lock wire. It is primarily used to secure fasteners on aircraft, ensuring that vibrations or other factors do not loosen during flight.
The usage of safety lockwire in this industry is not only a standard practice but a regulatory requirement to maintain aircraft safety and integrity.
In the automotive industry, safety lock wire is extensively used to secure elements of high-performance vehicles, racing cars, and motorcycles.
These vehicles often undergo severe vibrations and stresses, leading to the loosening of fasteners. Safety lockwire helps prevent any such incidents and ensures the proper functioning of vehicles, especially in high-stakes racing environments.
Safety lockwire also finds significant application in the oil and gas industry. It is used in securing fasteners and fittings in oil rigs, pipelines, and processing facilities.
The conditions in these facilities can be extremely harsh, with high pressures, vibrations, and corrosive elements. Safety lockwire ensures that the fasteners do not loosen or fall off, preventing possible leaks or accidents, and maintaining the integrity and safety of the entire operation.
Proper installation of the safety wire is as important as the lock wire itself. There are several techniques to secure fasteners effectively, where the most common are the Double Twist Method and the Single Twist Method.
The Double Twist Method is commonly used when securing two or more fasteners together. After threading the wire through the fasteners, equal lengths of the wire are twisted together between the fasteners.
The twisting creates a tight bond, preventing the fasteners from loosening under stress or vibration. This method is typically used in scenarios where multiple fasteners are in close proximity.
The Single Twist Method, on the other hand, is typically used when the lockwire is securing a single fastener. In this method, the wire is threaded through the hole of the fastener and then twisted around itself, forming a loop.
The remaining end of the wire is then twisted back onto itself to lock the loop in place. This is a simpler process but is also effective in preventing the disengagement of the fastener.
While the above methods are standard, it is vital to adjust your technique depending on specific applications. For example, the direction of the twist and the tightness of the wire may depend on the direction of rotation of the fastener, its size, and its material.
Always ensure to consult the guidelines provided by the manufacturer or industry standards for specific applications.
