Bonded washers are specialized fastening components designed to maintain tension beneath standard fasteners, preventing loosening due to vibration. These washers are typically installed on the nut side of the fastener assembly.

Our bonded washers are manufactured using premium materials including carbon steel grades Q195, Q235, 35K, 45K, 40Cr, 35CrMo, and 42CrMo, as well as stainless steel options SS304, SS316, and SS410. These materials ensure durability and corrosion resistance for various industrial applications.

The washers are available in multiple surface finishes including plain, zinc plated (clear/blue/yellow/black), black oxide, nickel plating, hot dip galvanized, mechanical galvanized, Geomet coating, and zinc-nickel alloy. This variety allows for selection based on specific environmental and performance requirements.

Our production capabilities include OEM and ODM services with flexible packaging options. We can accommodate custom labeling and carton box specifications to meet your specific requirements.
