Frequently asked question (FAQ)

Question: What is the purpose of using a round washer with a large outer diameter for wood applications?: Answer: When fastening components to wood, a round washer with an enlarged outer diameter distributes the load over a greater surface area. This prevents the fastener from sinking into the wood, reducing the risk of depression or damage to the material, ensuring a secure and stable connection.
Question: What materials are used for these washers?: Answer: The washers are made from Steel/SPCC (cold-rolled steel)
Question: What are the different thickness options for these washers?: Answer: Washers are available in thicknesses ranging from 0.3 mm to 45 mm, offering flexibility for different load-bearing requirements. Thinner washers are suitable for lightweight applications, while thicker options provide additional strength for high-load environments.
Question: How does the washer contribute to load distribution in fastening applications?: Answer: Washers distribute the load evenly across the fastening surface, preventing stress concentration on bolts, screws, and the material being fastened. This minimizes the risk of fastener loosening, material deformation, and structural failure, especially in soft materials like wood, aluminium, or plastic.
Question: Are these washers resistant to rust and corrosion?: Answer: Yes, the washers have various surface treatments such as Tricalent Chromate, Nickel Plating, and Bright chrome plating to prevent rust and oxidation. However, rust may occur depending on the usage conditions.
