In composite aircraft structures, they prevent carbon fiber panels from being crushed during fastener installation by distributing clamping forces more evenly.
NAS1056 refers to a specific developed by the Aerospace Industries Association (AIA) . These spacers are unthreaded, round fasteners designed to create precise gaps between two objects in an assembly. nas1056 spacers
Available in highly specific increments, such as 0.05" up to over 2 inches. Key Applications In composite aircraft structures, they prevent carbon fiber
Most often 300 Series Corrosion-Resistant Steel (CRES), such as 303, 303 Se, or 304. These materials provide excellent corrosion resistance and are non-magnetic. Available in highly specific increments, such as 0
According to technical specifications from Lyn-Tron , these parts are "High Temperature, Non-Magnetic" sleeve-rivet spacers. They are governed by standards developed by the , ensuring that any NAS1056 part is interchangeable regardless of the manufacturer. Technical Specifications & Materials
They are for use as bearings or high-speed rotating components (no internal clearance spec).
