Professional Applications & Engineering Value
This 82° countersunk washer is engineered to address common challenges in precision assembly, such as achieving a seamless finish and maintaining structural integrity. Made from 18-8 Stainless Steel, it offers excellent resistance to rust and corrosion, making it suitable for outdoor, marine, or chemical-exposed settings. The 0.531" OD and 0.21" ID are meticulously designed to match No. 8 screws, ensuring a snug fit that distributes clamping force evenly. This prevents sinkage into softer materials and reduces the need for re-tightening, saving time in aerospace, automotive, and machinery applications. Its flush mount capability is critical for applications where protruding hardware could cause obstruction or safety hazards, enhancing both performance and aesthetics.
