The 95-110021 Washer is a structural aircraft washer used in wing flat spar fitting assemblies. It is designed for high-load airframe connections where it supports fastener load distribution, alignment, and surface protection between structural components in the wing structure.

This washer is typically installed in critical wing spar and fitting locations where consistent load transfer and resistance to vibration and fatigue are required. It is manufactured to aerospace-grade specifications for use in certified aircraft structures and maintenance operations.

Its primary features include:
Designed for wing spar and flat fitting structural applications
Provides load distribution in high-stress airframe joints
Helps maintain alignment in wing structural assemblies
Manufactured to aerospace-grade tolerances
Suitable for fatigue- and vibration-critical environments
Used in certified aircraft structural maintenance and repair
High-strength metal construction for durability
Compatible with OEM aircraft wing hardware systems

Washers like the 95-110021 are used in aircraft wing structures because they help ensure secure fastening, distribute loads evenly across fittings, and maintain long-term structural integrity under aerodynamic and operational stresses.
