At a Glance: Precision metal pin/shaft replacement for the AirCraft AT0016 Air Ratchet Wrench—small part, big influence on smooth engagement.
When an air ratchet feels inconsistent, sticks, or doesn’t engage quite like it used to, it’s often a worn pin or shaft that’s throwing the mechanism out of harmony. The AirCraft AT0016-05 Pin is a purpose-made replacement component for the AirCraft Air Ratchet Wrench (AT0016 series). Designed to sit accurately in its mating parts, this pin helps maintain correct alignment and controlled movement inside the tool—so the action stays smooth, responsive and dependable. Ideal for repairs, rebuilds and preventative servicing where precision matters.
AirCraft replacement pin for accurate fit and dependable internal movement
Pins and shafts act like the “hinges and guides” inside your tool—keeping parts aligned and helping mechanisms move as intended. Replacing a worn, scored or bent pin can restore proper feel and reduce premature wear on surrounding components.
Extra Information
Intended as a spare part for AirCraft Air Ratchet Wrench assemblies (AT0016 series).
Replace if the pin shows scoring, flat spots, bending, corrosion, or if the mechanism feels rough or inconsistent.
During servicing, keep parts in order—pins may be similar in appearance but different in length/steps.
If a parts diagram is available under the Documents tab, use it to confirm the exact location and orientation of this component.
Pro Tip
Before reassembly, wipe the bore and mating surfaces clean and apply a light film of pneumatic tool oil—clean fit + light lubrication helps the pin move freely and last longer.
