Product Description
Part 12272 is a tab washer lockplate that prevents vibration-induced loosening of mounting bolts and nuts on aircraft accessories. This steel lockplate features bendable tabs that form against fastener flats to create positive mechanical locking. Installation involves bending one tab against a bolt or nut flat per FAA AC 43.13-1B guidance, conforming to NAS513 standards.
Replace the lockplate if tabs become deformed beyond reuse. Commonly used in engine accessory mounting, control system fasteners, and structural attachment points where vibration resistance is critical.
