bolt securing washers

The DIN 25201 bolt lock washers are an essential component to prevent loosening of threaded joints subject to vibration and dynamic loads. Their innovative design, consisting of two toothed elements, ensures effective locking by preventing relative movement between nut and bolt. Compared to traditional fastening systems, DIN 25201 washers offer superior strength, reducing the need for maintenance and improving the reliability of assemblies. Made of high-strength steel and available with corrosion protection treatments, these washers are used in critical areas such as automotive, railway, aerospace and general mechanical engineering. For safe and efficient fastening solutions, choose non-screwing washers conforming to DIN 25201 standards.
