Zeron Fastners
Monel 400 Washers
Monel 400 Washers are indispensable components in any high-performance bolting assembly, manufactured from the resilient nickel-copper alloy Monel 400 (UNS N04400). As a trusted manufacturer and supplier, Zeron Fasteners produces these washers to precise dimensional standards. The primary function of this product is to distribute the load of a threaded fastener (like a bolt or nut) evenly across the substrate, preventing damage and ensuring the assembly remains tight. Known for exceptional resistance to high-velocity seawater and various corrosive media, the key application of these Monel 400 Washers is in marine hardware, chemical processing piping, pump and valve components, and heat exchangers, where standard carbon steel or common stainless steel materials would rapidly degrade.
