Hexagon Flange Bolts DIN 6921 GALVANIZED are high-quality fasteners that are designed to provide exceptional strength and durability in a variety of applications. These bolts are made from premium materials and are finished with a high-quality galvanized coat to ensure long-lasting performance even in harsh environments. The flanged head design of these bolts provides a wide bearing surface that distributes the clamping load over a larger area. This helps to prevent damage to the surface of the materials being fastened, as well as providing a more secure and stable fastening. The hexagon shape of the head also means that it can be easily tightened or loosened using a standard wrench or socket.
