AirCraft AT0016-37 Spring For Air Ratchet Wrench
At a Glance: Replacement coil spring for the AirCraft AT0016 air ratchet—provides the tension needed for crisp engagement and dependable control.
Tiny part, big responsibility. The AirCraft AT0016-37 Spring is a replacement coil spring used in the AirCraft Air Ratchet Wrench (AT0016 series) to apply consistent tension within the ratchet head or selector mechanism. Springs are what keep detents positive, pawls seated, and moving parts returning the way they should. When a spring fatigues, breaks, or loses its shape, the tool can feel loose, inconsistent, or start slipping because components aren’t being held firmly in place. Replacing the spring restores that “click-into-place†confidence and helps the ratchet operate smoothly and reliably.
In ratchet assemblies, proper spring tension prevents partial engagement and reduces wear on teeth, pawls and selector parts. A fresh spring helps the mechanism seat correctly and stay there under load.
