Made from 18-8 stainless\nsteel and sized for a 5\/8 inch bolt, they sit under a bolt head or nut to\nspread clamping force over a wider area while standing up to moisture and\nweather that would rust ordinary plated washers. The washer seats around the\nfastener and bridges the mounting hole, distributing pressure so the bolt or\nnut bears over a broader surface for a firm, well-seated connection. It\nprotects the material surface from damage while keeping the joint evenly\nloaded and secure under use. Made from 18-8 stainless steel, the washer\nresists rust, corrosion, and staining far better than zinc-plated steel,\nholding up to moisture, humidity, salt air, and repeated washdown. That makes\nit a lasting choice for exposed connections where a plated washer would\ncorrode and streak over time. Use these washers for outdoor, marine, coastal,\nand wet or washdown settings, including decks, docks, boats, railings, and\nfixtures exposed to the elements. They suit any job where corrosion resistance\nmatters. The corrosion resistance also means the washers will not streak or\nstain the surrounding surface over time. This pack provides a ready supply for\noutdoor, marine, and moisture-exposed fastening projects around the home,\ndock, and shop. From the Manufacturer Used in applications with nuts and\nbolts. The flat washer provides a greater bearing surface which helps prevent\na nut or bolt head from tearing through the material. Flat washers are\ncommonly used in decks and fence building.
