Aircraft Rivnuts - NAS1329 & NAS1330 Series
Cadmium Plated Blind Threaded Inserts | EU Stock
Your European Source for Aviation Rivnuts
|
Airpart Supply stocks a comprehensive range of NAS specification rivnuts in our Dublin warehouse, providing fast delivery across the European Union for maintenance organisations and aircraft operators requiring permanent threaded anchor points. Rivnuts, also known as blind rivet nuts or threaded inserts, are essential aircraft hardware components that provide permanent threaded anchor points in sheet metal where back-side access is not possible. These blind fasteners are installed from one side of the material and create a strong, reliable thread for machine screws, making them ideal for airframe repairs and modifications. Our range includes NAS1329 (low-profile head) and NAS1330 (standard head) series rivnuts in cadmium plated finish for corrosion protection. These are used extensively throughout general aviation aircraft including Cessna, Piper, and Beechcraft aircraft for permanent fastening applications. Available in thread sizes 6-32, 8-32, and 10-32 with various grip ranges to suit different material thicknesses. All parts meet NAS specifications and ship from our EU warehouse with full traceability documentation. |
Rivnut Dimensions Reference
Understanding Rivnut Specifications
Selecting the correct rivnut requires understanding these key dimensions:
Thread SizeInternal thread that accepts the mating screw (6-32, 8-32, or 10-32). |
Grip RangeMaterial thickness the rivnut can accommodate. Critical for proper installation. |
Hole SizeRequired hole diameter for installation. Must be accurately drilled. |
Body DiameterOuter diameter of the rivnut body that sits in the drilled hole. |
Head HeightHeight of flange above panel surface. NAS1329 has lower profile than NAS1330. |
Head DiameterFlange diameter that bears against the panel surface when installed. |
LengthOverall length of the rivnut before installation. |
Installed LengthLength after installation when body has been collapsed to form blind head. |

NAS1329 vs NAS1330 - Choosing the Right Series
NAS1329 - Low Profile HeadHead Height: .032" (6-32, 8-32) / .038" (10-32) Best for: Applications where minimum protrusion above the surface is required Advantages: Lower profile, better for tight clearance areas, smoother external surface Applications: Exterior skin panels, areas requiring flush appearance, limited clearance zones |
NAS1330 - Standard Profile HeadHead Height: .063" Best for: Applications where higher head strength and bearing area are needed Advantages: Larger flange for better load distribution, increased pull-through resistance Applications: Interior panels, structural attachments, high-load applications |
Understanding Key-Locked (K Suffix) Rivnuts
Standard RivnutsStandard rivnuts (without K suffix) rely on friction between the collapsed body and the hole wall to resist rotation. Suitable for most applications where moderate torque is applied during screw installation. |
Key-Locked Rivnuts (K Suffix)Key-locked rivnuts feature a keyed body that requires a corresponding keyed hole. This provides positive anti-rotation that prevents the rivnut from spinning during screw installation, even under high torque. Required for applications with repeated screw removal/installation cycles. |
