PREMIUM COPPER MATERIAL – Made from high-quality copper, these washers provide excellent durability, resistance to corrosion, and superior conductivity, making them ideal for both mechanical and electrical uses.
SMOOTH SURFACE FOR REDUCED FRICTION – The smooth surface of each washer minimizes friction between fasteners, which helps prevent leakage, reduces wear, and ensures a secure fit.
PREVENTS LOOSENING & DISTRIBUTES PRESSURE – Copper washers help distribute pressure evenly across surfaces, reducing the risk of loosening over time, and ensuring more stable and reliable connections.
COMPREHENSIVE SIZE SELECTION – This set includes 100 washers in 7 sizes, providing a wide range of sizes that are suitable for various bolts, screws, and fasteners.
CONVENIENT STORAGE CASE – The washers come neatly organized in a clear plastic storage case with 8 or 9 individual compartments, making it easy to access the right size when you need it.
