This range of heavy-duty, oversized flat washers is engineered to provide enhanced load distribution and structural support for demanding assembly projects. Manufactured from marine-grade 316 stainless steel with an increased thickness and wider outer diameter, these gaskets distribute clamping pressure over a larger surface area, preventing bolt heads or nuts from biting into or crushing connected materials.
Oversized & Thickened Profile: Extra surface coverage and thickness help bridge enlarged or irregular holes while reducing surface stress under heavy loads.
Marine-Grade 316 Stainless Steel: Offers maximum resistance to salt water, harsh chemicals, oxidation, and severe weather conditions compared to standard grades.
Surface Protection: Acts as a smooth bearing surface between fasteners and mating materials to prevent wear, marring, and surface deformation.
Wide Dimensional Compatibility: Designed to fit standard metric bolts, screws, and threaded rods across industrial, marine, automotive, and outdoor applications.
