Aircraft Flat-Type Tinnerman Nuts
Spring Steel Speed Nuts for Mid-Panel Mounting | EU Stock
Your European Source for Flat-Type Tinnerman Speed Nuts
|
Airpart Supply stocks a comprehensive range of aircraft Flat-Type Tinnerman nuts in our Dublin warehouse, providing fast delivery across the European Union for maintenance organisations and aircraft operators. Flat-Type Tinnerman nuts, also known as flat speed nuts or panel nuts, are essential aircraft hardware components designed for quick assembly where the fastening location is away from panel edges. These self-retaining fasteners provide a threaded receptacle for machine screws while maintaining a low profile, making them ideal for airframe applications where clearance is limited. Manufactured from spring steel for durability and reliable thread engagement, Flat-Type Tinnerman nuts are used extensively throughout general aviation aircraft including Cessna, Piper, and Beechcraft aircraft for securing interior panels, instrument mounts, and cabin trim where mid-panel fastening is required. Our range covers screw sizes #4 through #10 to suit different installation requirements. All parts meet aviation specifications and ship from our EU warehouse with full traceability. |

LengthOverall length of the nut body. Determines installation clearance behind the panel surface. |
WidthWidth across the nut body. Important for spacing between adjacent fasteners and panel cutout requirements. |

Selecting the Right Flat-Type Tinnerman Nut Size
#4 Size (A1776-4Z1D)Smallest size for light-duty applications. Ideal for small interior trim pieces, light plastic panels, and decorative covers where minimal load is applied. |
#6 Size (A1777-6Z1D)Common size for general interior panel work. Suitable for cabin trim, headliners, and standard interior access panels on most light aircraft. |
#8 Size (A1778-8Z1D)Medium-duty applications requiring additional thread engagement. Recommended for instrument panel mounting, heavier interior panels, and equipment covers. |
#10 Size (A1779-10Z1D)Largest size for heavier-duty requirements. Best for floor panels, baggage compartment covers, and applications where increased holding strength is needed. |
