Aerospace Bolts

With roughly 92,000 bolt line items, bolts are the largest single category in the Instaparts catalog of 266,000+ aerospace parts. Aircraft bolts carry the loads that matter most: wing attach fittings, control surface hinges, landing gear trunnions, and engine mounts all depend on bolted joints designed around a specific standard, material, head style, and grip length. Substituting "a bolt that fits" is never acceptable in aerospace — the drawing callout defines the part, and the part must arrive with documentation proving it is what it claims to be.

The specification landscape spans several generations of standards. AN3 through AN20 hex-head bolts are the classic general-purpose airframe bolts, still called out across legacy fleets and general aviation. The NAS6203–NAS6220 series provides close-tolerance hex-head bolts for net-fit and interference holes, while NAS144–NAS158 and MS20004–MS20024 internal-wrenching bolts deliver 160 ksi tension capability where head clearance is tight. Boeing platforms rely heavily on the proprietary BACB30 bolt family, and Airbus programs call out ABS and ASNA standard parts along with EN metric standards. Instaparts catalogs all of these families, so you can search and quote by exact part number.

Every bolt we supply moves through our AS9120 Rev B certified quality management system. Instaparts, a division of RFQ2Go, Inc. based in Toronto, Canada, sources exclusively from approved suppliers and applies counterfeit-prevention controls aligned with AS6081 — critical for high-strength fasteners, which remain one of the most frequently counterfeited commodity groups in aerospace. Shipments include certificates of conformance, and lot traceability is maintained from receipt through delivery.

Bolted joints rarely travel alone. Many of the same drawings specify aerospace screws for lighter attachments, aerospace rivets for skin and stringer work, and aerospace shims to control joint fit-up.
