Product DescriptionProduct DescriptionWe usually use glue to bond the wide-tooth surfaces into a pair, making installation easier and improving efficiency.DIN25201 double-layer self-locking washer is a high-performance anti-loosening washer, consisting of two interlocking parts. It adopts the wedge-locking principle and multi-tooth surface engagement design, effectively preventing bolts from loosening under high vibration and dynamic loads. Its unique double-layer design not only enhances connection strength but also ensures long-term stability in extreme environments. It is widely used in fields requiring high safety and reliability, such as railways, wind energy, heavy machinery, automobile manufacturing, and construction engineering. Stainless Steel 316 WasherStainless Steel 316 washers are highly resistant to corrosion, making them ideal for marine environments, chemical industries, and high-temperature applications. Their ability to resist chloride corrosion makes them the material of choice for industrial applications requiring superior corrosion resistance. The oxidation resistance and high-temperature endurance of 316 stainless steel ensure reliable connections and long-term stability under harsh conditions.Other materials and finishes are availablemerit65Mn + DacrometSuperior corrosion resistance and high-strength performance.65Mn + Black OxideEnhanced wear resistance and anti-corrosion properties.Stainless steel 316 + Natural PolishingExcellent rust protection with a clean, bright finish.Stainless steel 304 + Natural PolishingHighly corrosion-resistant, ideal for harsh environments.SpecificationProduct ApplicationsKey Application Features1.
