Aerospace Pins
Clevis pins, taper pins, cotter pins, and spring pins meeting NAS, AN, and MS specifications. Instant online pricing from an AS9120 certified distributor.
Aerospace Pin Types
We stock a full range of aircraft pins meeting AN, NAS, and MS specifications for structural, mechanical, and safety applications.
Clevis Pins
Headed pins used with cotter pins or safety wire to secure clevis joints in flight control linkages, landing gear assemblies, and structural connections.
Taper Pins
Precision ground pins with a standard 1:48 taper for alignment and retention in control surface hinges, bearing housings, and structural fittings.
Cotter Pins
Split pins used to lock castle nuts, clevis pins, and other fasteners against rotation or withdrawal. Essential safety hardware for flight-critical assemblies.
Spring Pins (Roll Pins)
Slotted tubular pins that compress during insertion for a secure interference fit. Used for alignment, pivot points, and fastener retention in aircraft assemblies.
Dowel Pins
Precision-ground cylindrical pins for accurate alignment and positioning of mating components in jigs, fixtures, and structural assemblies.
Quick-Release Pins
Spring-loaded pins for rapid assembly and disassembly of access panels, cowlings, and inspection covers. Ball-lock and push-pull configurations available.
Available Materials
Alloy Steel (Cadmium Plated)
High-strength pins for structural and flight-critical applications. Cadmium plating provides corrosion protection per QQ-P-416.
CRES (Corrosion-Resistant Steel)
300-series stainless steel pins for corrosion-prone environments. Used in external structures, landing gear, and marine-adjacent applications.
Aluminum Alloy
Lightweight pins for non-structural applications, alignment, and low-load retention. Often anodized for corrosion resistance.
Inconel & Specialty Alloys
High-temperature pins for engine and exhaust applications where standard alloys cannot withstand operating temperatures.

Your Trusted Source for Aircraft Pins
Aerospace pins are essential safety and structural components used throughout aircraft assemblies. From clevis pins securing flight control linkages to cotter pins preventing castle nut rotation, every pin must meet exact specifications for material, dimensions, and finish. Using the wrong pin — or a pin from an unqualified source — can compromise airworthiness.
Instaparts carries thousands of aerospace pins meeting AN (Air Force-Navy), NAS (National Aerospace Standard), and MS (Military Standard) specifications. Our inventory includes clevis pins, taper pins, cotter pins, spring pins, dowel pins, and quick-release pins in alloy steel, stainless steel, aluminum, and specialty alloys. Every pin ships with full material traceability and certificates of conformance.
