M12/M14/M16/M18 304 Stainless Steel Flat Washers Enlarged Thickened Round Metal Washers for Machinery & Construction

Our 304 Stainless Steel Flat Gaskets (also called enlarged thickened round metal washers, screw meson washers) are high-performance sealing and spacing fasteners, engineered for industrial, machinery, construction, and plumbing applications. Crafted from premium 304 stainless steel, these gaskets deliver exceptional corrosion resistance, rustproof performance, and durability—perfect for long-term use in indoor, outdoor, and humid environments.

 

Available in standard sizes M12, M14, M16, M18, these flat gaskets feature an enlarged, thickened design that enhances load-bearing capacity and sealing performance. The round metal construction ensures even pressure distribution, effectively preventing leakage, reducing friction between screws/nuts and surfaces, and protecting equipment or material surfaces from damage during installation and use.

 

Designed as screw meson washers, they are widely used to seal, insulate, and space components in machinery assembly, construction projects, plumbing fixtures, industrial equipment, and hardware installations. The 304 stainless steel material resists rust, corrosion, and wear, making them suitable for both heavy-duty industrial use and daily maintenance tasks.

 

Whether you’re securing machinery components, sealing plumbing connections, or reinforcing hardware installations, these enlarged thickened flat gaskets combine reliability, versatility, and durability to meet all your sealing and spacing needs.
