The EC1075-012-06SS is a stainless steel Tinnerman (dimpled/countersunk) aviation washer designed for use with #6 countersunk screws (100° head). It is commonly used in aircraft sheet metal and fairing installations where a low-profile, vibration-resistant fastening surface is required.

This washer is an alternative to DP1075-12SS and belongs to the EC1075 series of aviation-grade countersunk washers. It helps distribute load on thin aluminum skins and prevents pull-through or deformation around fastener holes.

Its primary features include:
Stainless steel aviation-grade construction
Designed for #6 100° countersunk screws
Low-profile Tinnerman/dimpled design for flush installation
Helps distribute load on thin sheet metal surfaces
Prevents fastener pull-through and skin deformation
Corrosion-resistant for aviation environments
Common in aircraft interior, exterior fairings, and panels
FAA-standard aviation hardware (AN/MS equivalent category)

This specific EC1075-012-06SS washer is widely used in general aviation sheet metal assembly because it provides a clean flush finish while maintaining structural support in lightweight aircraft skins and panels.
