Aircraft U-Type Tinnerman Nuts

Spring Steel Speed Nuts for Panel Edge Mounting | EU Stock

Your European Source for U-Type Tinnerman Speed Nuts

Airpart Supply stocks a comprehensive range of aircraft U-Type Tinnerman nuts in our Dublin warehouse, providing fast delivery across the European Union for maintenance organisations and aircraft operators.

U-Type Tinnerman nuts, also known as speed nuts or clip nuts, are essential aircraft hardware components designed for quick assembly on panel edges. These self-retaining fasteners grip onto the edge of sheet metal panels, providing a threaded receptacle for screws without requiring back access - making them ideal for airframe applications where access is limited.

Manufactured from spring steel for durability and reliable thread engagement, U-Type Tinnerman nuts are used extensively throughout general aviation aircraft including Cessna, Piper, and Beechcraft aircraft for securing inspection panels, access covers, fairings, and interior trim.

Our range covers screw sizes #6 and #8 with various panel thickness options to suit different installation requirements. All parts meet aviation specifications and ship from our EU warehouse.
