When fastening softer materials like wood, plastic, or sheet metal, pressure distribution matters. Fender washers—large-diameter machined washers—spread clamping load over a wider area. With CNC machining, variance is minimal, eliminating warping under torque.
These washers prevent bolt heads from sinking, particularly in filament-wound or resin-rich panels. Their fit and smooth finish prevent part damage, making them ideal for furniture manufacturing, composite panel fastening, and body panels in electric vehicles.
