What is Lock Wire?

Lock wire, commonly known as safety wire, is an extremely versatile tool for a variety of industries. Brookfield Wire’s design ensures that fasteners remain tight for dependable performance. Our locking device is essentially a safety feature that prevents the loosening of fasteners such as nuts, bolts, and screws.

Industries with high-vibration environments require dependable lockwire. The continuous shaking, jolting, and jarring of industrial applications tends to loosen the hold of fasteners. As a result of a loosening bolt, dangerous mechanical failures can occur. When it comes to mission-critical flight controls, throttle mechanisms, and braking devices, failure is not an option.

Safety wire is thread through fasteners in order to cancel out the torque force of fasteners attempting to unwind. Therefore, lock wire is a critical tool to ensure not only top performance but also for the safety of your team.
