Professional AN960 Light Series Washers for European Aviation

Airpart Supply stocks comprehensive ranges of AN960 light series flat washers from our Dublin warehouse, providing European aviation customers with immediate access to FAA/PMA approved hardware. AN960 washers are thin, lightweight flat washers manufactured to precise aerospace specifications for use throughout aircraft structures, engine installations, and electrical systems. These washers distribute loads across bolt heads and nuts while maintaining minimal stack height in weight-sensitive applications. We supply AN960 washers in both cadmium-plated steel and corrosion-resistant stainless steel materials, covering sizes from #4 through 3/4 inch diameters. All washers meet stringent NAS1149 specifications and include full traceability documentation for Cessna, Piper, Beechcraft, and other general aviation aircraft maintenance. European customers benefit from Dublin-based inventory, eliminating post-Brexit customs complications and providing 2-5 business day delivery throughout the EU with proper VAT handling and EASA-compliant certification.

AN960 Washer Technical Specifications

AN960 light series washers are manufactured to NAS1149 specifications, which superseded the original AN960 standard while maintaining dimensional compatibility. These washers feature precisely controlled thickness tolerances of 0.016 inch for smaller sizes (#4 through #8) and 0.032 inch for larger sizes (#10 through 3/4 inch).

Material Options & Applications

Cadmium-Plated Steel (NAS1149F Series): Standard choice for general aircraft hardware applications, offering excellent corrosion protection and electrical conductivity. Suitable for interior structures, engine accessories, and protected environments. The cadmium plating provides superior thread lubrication and prevents galling during installation.

Corrosion-Resistant Stainless Steel (NAS1149C Series): Recommended for external installations, high-moisture environments, and applications requiring non-magnetic materials. Stainless steel washers eliminate cadmium exposure concerns and provide excellent durability in marine environments or coastal operations. Used extensively in Continental and Lycoming exhaust systems and external control linkages.

AN960 Washer Applications in Aircraft Maintenance

Airframe Structure Applications

AN960 light series washers are essential components in aircraft primary structures, where they distribute loads from AN3, AN4, and AN5 bolts across aluminum alloy skin and longerons. The thin profile minimizes stack height in confined areas while maintaining adequate bearing surface. Common applications include wing attachment fittings, fuselage frames, and empennage structural joints on Cessna, Piper, and Beechcraft aircraft.

Engine Installation Hardware

Engine mount assemblies and vibration isolators require AN960 washers to provide proper bearing surfaces under dynamic loading conditions. These washers prevent bolt heads from embedding into softer materials during engine operation and facilitate inspection of torque retention. Used extensively with Lycoming and Continental engine accessories including alternator brackets, oil cooler mounts, and exhaust system attachments.

Systems & Accessories Mounting

AN960 washers secure numerous electrical components, avionics installations, and interior trim assemblies throughout the aircraft. The minimal thickness allows multiple washers to be stacked when precise adjustment is required without exceeding thread engagement limits. Applications include instrument panel installations, radio rack mounting, seat track attachments, and interior panel fastening in both certified aircraft and experimental/amateur-built projects.

Control Systems & Linkages

Flight control systems utilize AN960 washers in bellcrank assemblies, push-pull rod connections, and trim actuator installations where precise clearances must be maintained. The washers prevent binding while allowing free movement of control surfaces. Stainless steel versions are preferred for external controls exposed to weather, while cadmium-plated washers serve interior installations. Proper washer selection ensures smooth control feel and prevents premature wear of aluminum brackets.

Why Source AN960 Washers from Our Dublin Warehouse?

Immediate European Availability

Our Dublin facility maintains comprehensive AN960 washer inventory covering all standard sizes in both cadmium-plated and stainless steel materials. European customers receive same-day dispatch on in-stock items, eliminating the delays associated with transatlantic shipping or UK customs processing. This local availability supports AOG situations and scheduled maintenance events where aircraft hardware requirements are time-critical.

Fast EU Delivery & Logistics

Shipping from our Dublin warehouse provides 2-5 business day delivery to most European destinations including Germany, France, Spain, Italy, Netherlands, Belgium, and throughout the EU. Our free express shipping programme on qualifying orders eliminates shipping costs for larger hardware purchases. Consolidated shipments of AN bolts, lock washers, and AN960 flat washers reduce freight expenses.

EU VAT Compliance & Customs Handling

As an Irish-registered company, we handle all VAT requirements for European customers, providing proper documentation and eliminating customs delays. EU customers receive streamlined invoicing with appropriate VAT treatment based on their location, whether B2B or B2C transactions. This simplifies purchasing compared to imports from non-EU suppliers where customs clearance adds time and administrative burden to every shipment.

EASA Compliance & Certification

All AN960 washers supplied by Airpart include full traceability documentation and manufacturer certifications meeting EASA Part-21 requirements. We provide certificates of conformance with each shipment, essential for Part-145 maintenance organisations and continuing airworthiness management throughout Europe. Our documentation supports both commercial operations and private aircraft maintenance in EU member states, ensuring regulatory compliance for Cessna, Piper, and other aircraft types.

Technical Support for European Customers

Our technical team provides expert guidance on AN960 washer selection, proper installation procedures, and material compatibility considerations. We assist with aircraft-specific hardware requirements, helping European customers identify correct specifications from maintenance manuals and service bulletins. Technical support extends to questions about safety wiring techniques, torque values, and inspection criteria for installed hardware.

Complete Hardware Solution

Beyond AN960 washers, we stock comprehensive ranges of AN bolts, AN970 lock washers, castle nuts, cotter pins, and safety wire. This allows European customers to source complete hardware kits from a single supplier, reducing procurement complexity and freight costs. We support both routine maintenance and major inspection requirements with fast, reliable service from our Dublin location.
