Deskripsi Produk

DIN 603 Mushroom Head Carriage Bolts are high-strength fastening components designed with a smooth round mushroom head and a square neck under the head. The square neck helps prevent the bolt from rotating during installation, making it ideal for wood, steel structures, machinery, construction, furniture, guardrails, and general industrial fastening applications.

Made from carbon steel and finished with zinc plating, these carriage bolts offer reliable strength, corrosion resistance, and a clean silver appearance. The smooth mushroom head provides a neat surface finish and reduces the risk of snagging, making it suitable for exposed fastening positions.

These bolts are commonly used together with hex nuts and washers to create a strong and secure connection.
