Lock Wire

Metal Associates works with wire manufacturers that custom draw round, flat, square and shaped wire to your exact specifications.

We supply our customer’s lock wire and safety wire needs in a variety of gauges and materials, depending on the application. Lockwire or safety wire is used as a positive locking device to prevent the loosening or falling out of fasteners from factors such as vibration, and can also be used to show that a fastener has been tightened properly. It is commonly used in aerospace and car industries for throttle assemblies or safety guards where extreme reliability is needed. When using lock wire, it is threaded through a hole in the fastener, twisted, then anchored to a second fastener, and twisted again.

Whatever application or lock wire need you may have, Metal Associates can supply you with the most reliable safety wire products.

In addition to the alloys below, Metal Associates is now a supplier of Cadmium Plated Copper Wire (lock wire) in CY10, CY13, CY15, CY20, CY32, and CY40 Coppers.

Lock Wire Applications
Metal assemblies with fasteners are common in many different industries. Most machinery is fitted together with fasteners and can be subject to heavy impacts and vibrations during operation. Lock wire is used in applications like these to prevent the fastener from moving. Some examples of this include:
  • Airplane cabins
  • Automotive assemblies
  • Specialize machine parts
  • Heavy duty U bolt locks
  • Pipe fittings
Metal Associates is proud to supply locking wire to industries who need to build their products with a high degree of safety and reliability.
