Frequently Asked Questions

What is safety lock wire, and why is it used?

Safety lock wire is a type of wire used to secure fasteners, bolts and other components in place to prevent them from loosening due to vibration or other operational forces. It’s commonly used in aerospace, automotive and industrial applications where safety and reliability are critical.

Safety lock wires are typically made from materials like stainless steel, Inconel or Monel. These materials offer excellent resistance to corrosion, heat and mechanical stress, ensuring durability in challenging environments.

Safety lock wire comes in various diameters to accommodate different applications. The appropriate size depends on the specific requirements of your project or industry standards.

The choice of size and material depends on factors such as operating environment, temperature and the load on the fastener. Consult the equipment manufacturer’s guidelines or industry standards like ASME or MIL-SPEC for specific recommendations.

No, safety lock wire is not reusable. Once it has been applied and removed, it should be discarded to ensure the integrity and reliability of the wiring in future applications.

 

You will need safety wire pliers (for twisting and securing the wire), wire cutters and possibly a pair of needle-nose pliers for tight spaces. Proper tools ensure the wire is installed correctly and securely.

Yes, safety lock wire must meet certain industry standards, such as those outlined in ASME, SAE or military specifications like MIL-DTL-83420. These standards ensure consistent performance and safety.

Yes, certain materials like Inconel and stainless steel are suitable for extreme temperature environments. Check the wire’s specifications to ensure it meets the temperature requirements of your application.
