Aerospace Nutplates
Roughly 2,400 nutplates for access panels, fairings, and blind-side fastening. MS21059 and MS21075 self-locking anchor nuts in one-lug, two-lug, corner, floating, and fixed styles, ready to order with full AS9120 traceability.
Aerospace Nutplate Types
From two-lug floating anchor nuts to corner styles and gang channels, we cover the nutplate families that put permanent, self-locking threads behind aircraft structure.
Floating Nutplates
A floating nut element compensates for small hole misalignments, easing panel installation. Two-lug floating families such as MS21059 and MS21075 differ in height and mounting details, so order the exact drawing callout.
Fixed Nutplates
Non-floating anchor nuts for accurately located holes, such as the MS21047 two-lug family. The self-locking element is held rigidly to the plate, giving a repeatable thread position behind the structure.
One-Lug & Corner Styles
Where edge distance or flanges leave no room for a standard two-lug pattern, one-lug and 90-degree corner nutplates, such as the MS21051 and MS21053 families, fit the available footprint.
Gang Channels
Gang channel assemblies carry a row of floating nut elements in a shared channel strip, typically used along access panel and fairing edges to speed installation and replacement of many fasteners at once.
Nutplate Materials & Options
Cadmium-Plated Alloy Steel
The standard for general structure, matched to plated steel screws and bolts. Heat-treated plates and locking elements deliver the strength and prevailing torque the specifications require.
CRES & A286
Corrosion-resistant and precipitation-hardened stainless nutplates for hot and corrosive zones such as engine, nacelle, and firewall areas, where plated alloy steel is unsuitable.
Locking & Sealing Options
Self-locking elements provide prevailing torque without a separate device, with dry-film lubricated threads on many variants. Sealed and dome styles serve positions where the drawing requires a fuel or pressure boundary.
Attachment Styles
Most nutplates rivet to structure through two small attachment holes, with countersunk rivets keeping the outer surface flush. Rivetless and bonded styles appear on some designs; the drawing defines the method.

Your Distribution Partner for Aircraft Nutplates
With roughly 2,400 nutplate line items in the Instaparts catalog of 266,000+ aerospace parts, we cover the hardware that makes aircraft panels removable. A modern airframe carries hundreds of access panels and fairings, and behind nearly every panel screw sits a nutplate: a permanently installed, usually self-locking threaded anchor attached to the blind side of the structure. The drawing callout defines the style, thread, and material, and substituting "a nutplate that fits" is never acceptable in aerospace.
The specification landscape is organized by footprint and float. Two-lug floating families such as MS21059 and MS21075 dominate on removable panels, where the floating element lets the screw find its thread despite tolerance stack-ups. Fixed styles such as MS21047 serve accurately located holes, while one-lug and corner patterns, such as MS21051 and MS21053, fit tight edge margins and flanged corners. For long rows of fasteners along panel edges, gang channel assemblies carry many floating elements in a single strip. Instaparts catalogs all of these families, so you can search and quote by exact part number.
Every nutplate 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. Shipments include certificates of conformance, and lot traceability is maintained from receipt through delivery, so the anchor hardware buried inside your structure has the same pedigree as the fasteners you can see.
Nutplate installations pull in hardware from across the catalog: aerospace rivets attach the plate to structure, aerospace screws provide the mating fastener, and aerospace nuts cover positions where a wrench can reach both sides. If your requirement covers multiple categories or a long bill of materials, send it through our quote page and our team will price the complete package.
Aerospace Nutplate FAQs
What is the difference between floating and fixed nutplates?
A floating nutplate holds its nut element in a small cage that allows slight radial movement, so the screw can find the thread even when hole positions vary within tolerance. A fixed nutplate holds the element rigidly for accurately located holes. The drawing decides which is required; floating styles dominate on removable panels.
How are nutplates installed?
Most nutplates rivet to the blind side of the structure through two small attachment holes, typically with countersunk rivets so the outside surface stays flush. Rivetless and bonded styles appear on some designs. The applicable process specification and drawing define hole preparation and the attachment method.
When would I use a one-lug or corner nutplate?
One-lug and corner styles exist for tight real estate. Where a flange, radius, or edge margin leaves no room for the standard two-lug footprint, a one-lug pattern, or a corner pattern with lugs at 90 degrees, fits the available space while still providing an anchored, self-locking thread.
What is a gang channel nutplate?
A gang channel carries a row of floating nut elements in a shared channel strip, typically used along access panel and fairing edges. Installing one channel replaces many individual nutplates, and on many designs the nut elements can be replaced without removing the channel.
What documentation comes with your nutplates?
Instaparts operates an AS9120 Rev B certified quality management system. Orders ship with certificates of conformance, lot traceability is maintained back to our approved suppliers, and counterfeit-prevention controls aligned with AS6081 are applied to every fastener purchase.
