TEC-MEC Iron Disc Washers 30-40mm 15-30mm

A disc washer (also known as a flat washer) is a type of washer that has a flat, circular shape with a hole in the center, designed to distribute the load of a fastener, such as a bolt, screw, or nut, over a larger surface area. This helps prevent damage to the material being fastened and reduces the chances of loosening due to vibration. Key Features of Disc Washers: Shape: A disc washer is typically round with a central hole. It has a uniform thickness and is flat, providing a large surface area for load distribution. Material: Disc washers are made from a variety of materials depending on the application. Common materials include: Steel (plain or galvanized for corrosion resistance) Stainless Steel (for corrosion-resistant applications) Brass (for electrical connections and non-corrosive environments) Plastic (for lightweight and non-metallic applications) Copper (for electrical or heat-dissipation needs) Load Distribution: The primary function of a disc washer is to distribute the load of a fastener (such as a bolt or screw) over a larger area to prevent damage to softer materials or surfaces, which could otherwise be deformed by the fastener. Size and Thickness: Disc washers come in various sizes, with diameters ranging from a few millimeters to several inches. The thickness of the washer typically depends on the load-bearing requirements, with thicker washers providing more strength and larger surface area. Central Hole: The hole in the center of the disc washer is typically designed to match the diameter of the bolt or screw used in the application. It provides a perfect fit for the fastener to pass through. Applications of Disc Washers: Mechanical and Industrial Applications: Disc washers are commonly used in machinery, vehicles, and industrial equipment to distribute pressure from bolts, nuts, and screws, especially when fastening to softer or delicate materials. Automotive Industry: Used to prevent damage to automotive components and provide a secure fastening in areas where vibrations or movement may loosen fasteners. Construction: In construction, disc washers are used for securing parts together, such as in structural steel connections, wooden assemblies, and securing bolts for various fixtures and fittings. Electronics and Electrical: In electronic and electrical applications, non-metallic disc washers (like plastic or rubber) can be used for insulation and preventing short circuits between conductive parts. Furniture and Woodworking: In woodworking, they prevent wood from being damaged by bolts and screws and are often used in furniture construction. Plumbing: Used in plumbing applications to seal joints or connections where bolts or nuts are used to fasten pipes and fixtures together. Advantages of Disc Washers: Load Distribution: The primary advantage of a disc washer is its ability to distribute the pressure of the fastener, preventing the material from being deformed or damaged under stress. Prevents Loosening: By providing a firm surface, disc washers help reduce the chances of fasteners loosening due to vibrations, especially in applications like automotive or machinery. Protection of Soft Materials: In applications involving softer materials (like wood, plastic, or aluminum), disc washers prevent the material from being crushed or marked by the fastener. Corrosion Resistance: Materials like stainless steel or galvanized steel help prevent rust and corrosion, extending the life of the fasteners and the materials they hold together. Versatile: Disc washers can be used in a wide range of applications, from light-duty jobs to heavy industrial uses, depending on the material and size chosen. Common Sizes and Types: Disc washers come in a range of sizes, typically matched to the fastener size being used. Some standard sizes include: Small Washers: Common for smaller fasteners, with diameters from 6mm to 20mm. Med
