Professional Applications & Engineering Value

These aluminum flat washers deliver exceptional engineering value in applications requiring corrosion resistance and regulatory compliance. The aluminum material inherently resists oxidation, making these washers ideal for outdoor equipment, marine hardware, and electronics enclosures exposed to moisture. With precise 0.197" ID and 0.5" OD dimensions, they provide perfect alignment for 3/16" rivet installations, preventing loosening and maintaining joint integrity in vibrating environments. The flat washer design distributes clamping force evenly across surfaces, protecting softer materials from deformation while the RoHS 3 and REACH compliance ensures these components meet the strictest environmental standards for industrial and consumer products.
