Does this safety lock wire meet aviation specifications?

Yes. This wire is manufactured to meet NASM20995C and MS20995C specifications, along with ASTM A580 Condition A and AMS5697 requirements, making it suitable for aviation, automotive, and industrial applications where compliance matters.

How does safety wire prevent bolts from loosening?

Safety lock wire secures fasteners by mechanically locking them in place, preventing rotation caused by vibration. When properly installed, it maintains tension and helps reduce the risk of fastener loosening in high-stress environments.

Which gauge should I choose for my application?

.020 is typically used for small fasteners, .032 is the most common for standard aviation use, .041 and .063 are used for larger or heavy-duty applications. Choose based on fastener size and required strength.

Will the wire snap or break during installation?

No. When used correctly, this stainless steel wire is designed to twist smoothly while maintaining strength and flexibility, reducing the risk of breakage during installation.

Do I need special tools to install this wire?

For best results, the Safety Wire Pliers are recommended to achieve consistent twisting and proper tension. Standard cutters can be used to trim the wire cleanly.
