About this product
The R0071000020700 washer is a flat, precision‑machined spacer designed to distribute the clamping load of a bolt or nut across a broader surface area, preventing damage to the underlying material and reducing the risk of fastener pull‑through. It is manufactured from corrosion‑resistant stainless steel.

PRODUCT DESCRIPTION

R0071000020700

  • Even Load Distribution: Spreads bolt or nut tension over a wider area to minimize localized stress and prevent material crushing under the fastener head.

  • Corrosion Resistance: Made from aerospace‑grade stainless steel with optional cadmium or nickel plating to guard against galvanic corrosion in mixed‑metal joints.

  • Non‑Marring Surface Finish: Polished bearing surface protects sensitive substrates, such as composite skins or painted panels, from abrasion during assembly and maintenance.

  • Vibration Dampening: Acts as a micro‑spring under fluctuating loads, reducing fastener loosening by absorbing minor movement and maintaining preload in high‑vibration environments.


  • Under bolt heads and nuts in primary and secondary airframe structures to ensure uniform load transfer.

  • As spacers in control‑surface hinge and linkage assemblies to maintain precise gap and alignment.

  • In equipment mounts and avionics racks, providing a stable bearing surface under dynamic loading.

  • Within hydraulic and fuel system flange connections, helping to maintain seal integrity and preload under pressure.


  • What materials are commonly used for aircraft washers?

Aerospace washers are typically made from stainless steel or titanium, with optional cadmium or nickel plating for additional corrosion protection.

  • Do washers affect torque values?

Yes, adding a washer can change the friction under the fastener head. Always verify torque settings against the manufacturer’s calibration curve that includes any washer or coating effects.

  • Can washers be reused during maintenance?

Flat washers may be reused if they show no signs of deformation, corrosion, or surface damage. Replace spring or locking washers with every fastener change.
