Safety-Wire, Lockwire & Fastener-Retention Tools

Fastener retention is a distinct, manual-mandated discipline in aircraft maintenance: critical bolts and B-nuts must be safetied so vibration can't back them off. This sub-category covers the tooling and engineered systems that do it — twist and reverse-twist lockwire pliers (manual and pneumatic), the faster safety-cable systems (ferrule-and-wire kits with their application tools) that replace traditional lockwire on many modern callouts, plus the lockwire spools and ferrules themselves. Buyers — line and base MRO, engine shops and airline engineering — choose by the maintenance manual's retention method, wire diameter and accessibility, where safety-cable's speed and consistency increasingly win on high-cycle tasks.
