• Environmental compliance with RoHS 3 and REACH standards, meeting global regulatory requirements
• Non-magnetic and spark-resistant properties, making them safe for electrical and explosive atmosphere applications

Professional Applications & Engineering Value

These brass flat washers deliver critical engineering value by solving common industrial challenges such as galvanic corrosion, vibration loosening, and surface degradation. The brass material inherently resists rust and chemical attack, making these washers ideal for marine, plumbing, and electrical enclosures where moisture is prevalent. With a Rockwell B60 hardness, they maintain structural integrity under repeated loading, while the precise 0.133" ID and 0.281" OD ensure optimal load distribution for No. 5 screws, preventing embedding and extending the life of assembled components. Their non-conductive and non-sparking nature adds safety in hazardous areas, providing a reliable solution for OEMs and maintenance teams across various sectors.
