What is Safety Lock Wire?

Safety Lock Wire is a vital component in countless applications and industries. Nearly everyone has experienced a situation where a nut, bolt, or screw has loosened itself over time (Eye glasses are a good example most people have dealt with). When it comes to mission critical flight controls, throttle assemblies, or safety guards, failure can not occur. Annealed locking wire is threaded through fasteners to counter act the torque force of a fastener attempting to back off. The lock wire silently ensures you stay safe, and that's an insurance policy you can't live without.
