AirCraft Steel Ball for Air Ratchet Wrench 3/8" (AT0015-40) for Model AT0015
At a Glance: OEM-fit hardened steel detent ball for the AirCraft AT0015 3/8" air ratchet wrench, used to create positive “click” positioning in the mechanism.
The AirCraft AT0015-40 steel ball is a replacement hardened ball used in the AirCraft AT0015 3/8" air ratchet wrench assembly. Steel balls are commonly used as detent elements—working together with a spring and a mating groove/seat—to provide a crisp “click” and hold a component securely in position. If the ball is missing, worn, or damaged, the tool may feel sloppy, fail to hold position, or lose its positive indexing. Replacing the AT0015-40 steel ball helps restore firm, reliable engagement after servicing.
It acts as a detent element, typically working with a spring to locate and hold parts in defined positions for consistent operation.
