DIN125 Zinc Plated Carbon Steel Flat Washers | Plain Round Washers Supplier

The DIN125 zinc plated carbon steel flat washer is a standard plain washer used together with bolts, screws, threaded rods, and nuts. Its flat circular surface helps spread tightening force over a larger contact area, protecting the connected material and supporting a more stable fastening result.

The washer is manufactured from carbon steel, making it suitable for common mechanical and structural fastening work where reliable strength and cost‑effective bulk supply are required. The surface is ordinary zinc plated, giving the washer a bright silver appearance and providing basic protection against oxidation during storage, transport, and normal indoor or general‑use environments.

DIN125 is a widely used metric washer standard. For this product, the grade should be understood as DIN125 standard flat washer type, not bolt strength grades such as 8.8, 10.9, or 12.9. If a buyer has special hardness, thickness, coating, or performance requirements, specifications can be matched according to order requirements.
