These flat washers are crafted from durable 304 stainless steel and are designed to fit with nuts and bolts. They come in different sizes and have a simple plain finish. Perfect for use in boat lifts, hoists, and rigging setups, they’re compatible with treated lumber and offer excellent resistance to corrosion. With a strong tensile strength and high resistance to vibrations, their load capacity varies based on their size. For best results, it’s recommended to use them without an additional flat washer. The quantity in each package varies depending on the size of the product. These washers meet industry standards such as ASME B18.21.1, DIN 127 B, and the United States Military Standard NASM 35338.
