Extra Heavy Extra Thick Fender Washers

Extra heavy vs extra thick fender washers

When even an extra thick fender washer is not enough, the extra heavy extra thick version adds still more material and diameter, giving the maximum bearing area and stiffness of the fender washer family. It spreads very high clamping loads across the widest surface while resisting cupping, dishing, and pull-through in soft or thin material. This suits heavy structural repair, large-diameter fasteners on wood and composite, and any joint where load and durability are both critical. Made from 18-8 stainless, it resists corrosion for outdoor and freshwater use.

Why choose extra heavy extra thick fender washers

• Maximum bearing: the widest, thickest fender washer for heavy loads.
• Resists deformation: maximum stiffness against bending and dishing.
• Corrosion resistant: 18-8 stainless resists rust in wet and outdoor use.
• Toughest pull-through resistance: for soft and thin material under load.

Common applications for extra heavy extra thick fender washers

• Heavy structural repair and reinforcement
• Large-diameter fasteners on wood and composite

• Outdoor and freshwater heavy-duty work
