Penny washers, also known as repair or mudguard washers, are large diameter washers designed to distribute the clamping force of a fastener over a wider area, preventing damage to the material being fastened. Their key features include a large outer diameter relative to the inner hole, and they are often made of stainless steel for corrosion resistance.
Benefits include preventing fasteners from pulling through soft materials, reducing stress on thin or soft materials, and enhancing the overall strength and longevity of joints.
