- Reliable strength and durability These flat washers offer high hardness and strong corrosion and rust resistance to provide durable, reliable support in any project. They are designed to fit securely and help ensure a solid, long-lasting connection. - Safe and durable material Made from 304 stainless steel, this washer is safer and more durable than ordinary stainless steel. It is non-toxic, highly resistant to corrosion, and hard enough to resist deformation, making it suitable for outdoor use in wet environments. - Function and performance Flat washers reduce friction between screws and nuts, increasing overall joint strength. They also spread the load over a larger surface area, improving load-bearing capacity and providing reliable connections for machinery. - Design and handling Compact and lightweight for easy handling and installation. The surface is smooth and burr-free for reduced wear and tear, with a steady, even force and low risk of slipping during use. - Key attributes Material: 304 stainless steel Function: reduce friction, distribute load, improve joint integrity Performance: high hardness, corrosion and rust resistance Design: flat washers, compact and lightweight, easy to install Compatibility: suitable for standard screws and nuts in a variety of fastener assemblies - Use scenarios Outdoor furniture and garden structures that are exposed to rain and humidity require durable fasteners with good corrosion resistance. Machinery and equipment assemblies where distributing load and improving joint strength are important for reliable operation. General hardware projects such as decks, fences, metal enclosures, and other outdoor or wet-environment constructions that need sturdy, long-lasting washers.
