Safety wire is common in the
aircraft and
racing industries as an extra precaution to keep vital
fasteners from loosening and parts falling off. Safety wire is commonly .020, .025, .032 or .041 inches in diameter and usually made of
stainless steel, but is also available in
Monel and
Inconel alloys for high temperatur applications and copper for break-away applications. It is threaded through a hole drilled into a fastener or part, then twisted and anchored to a second fastener or part, then twisted again, usually with the aid of safety wire pliers.
