Paolo Astori

What Paolo Astori does

Paolo Astori S.p.A. is an Italian, family-owned precision aerospace fastener manufacturer headquartered in Gattico-Veruno (Novara), in operation in aerospace since 1942 (corporate roots to 1927) and currently in its third generation of Campagnoli-family ownership. The company produces self-locking nuts, nut plates, barrel nuts, shank nuts, spline nuts, clip nuts, anchor nuts, hex and double-hex nuts, press nuts, washers, shims and collars — a catalog of more than 12,000 active part numbers — with a specialization in machining difficult aerospace alloys including Inconel 718, A286 and titanium.

The business model is a qualified-tier-2 supplier: Paolo Astori designs, qualifies, and produces fasteners and (since 2022) sheet-metal parts to OEM-specific standards under multi-year, part-number-level supply agreements, selling into airframe, engine and rotorcraft programs. Customers span commercial-aviation primes (Airbus, Boeing, COMAC, Embraer, Bombardier, Gulfstream, Dassault), defense primes (Lockheed Martin, Bell, Agusta Westland, Alenia Aeronautica), and aero-engine OEMs (Rolls-Royce, Pratt & Whitney, Safran/Aircelle), with active distribution into 46 countries. Revenue mechanics are driven by long-life aerospace programs (e.g., F-16, F-35, C919) and aftermarket replenishment rather than transactional sales.

Manufacturing is concentrated in a single ~500,000 sq ft site backed by NADCAP-accredited heat treatment, chemical processing, NDT and fluid distribution systems, EN 9100 / ISO 9001 / ISO 14001 / ISO 45001 / ISO 14064 certifications, US Defense Logistics Agency QSLM approval and NATO Cage Code A3856. Recent capital deployment — approximately $30 million since 2012, a ~50,000 sq ft expansion completed in 2022–2023, a new automated raw-materials warehouse and third miniload aisle in 2024, and on-site solar generation — signals capacity build-out aligned with expanding OEM scope rather than cyclical maintenance investment.
