The prevailing torque type hexagon nut is an all-metal fastener designed to provide reliable locking capabilities in various applications. Manufactured from hardened carbon steel, these nuts are hot dip galvanized to enhance their corrosion resistance, making them suitable for use in environments where exposure to moisture and other corrosive elements is a concern. Complying with ISO 7042 and DIN 6925 standards, these nuts feature a metric thread with a right-hand direction, ensuring compatibility with standard bolts and threaded rods that meet the same thread tolerance specifications. The design of the hexagon head allows for easy installation and removal using conventional tools, while the prevailing torque feature ensures that once tightened, the nut remains securely in place, reducing the risk of loosening due to vibrations or dynamic loads. The threads are tapped after the galvanizing process, ensuring that the critical engagement area remains free of coating, which could interfere with the fit. This design consideration does not compromise corrosion protection, as the threads are shielded by the zinc layer of the mating part. These nuts are ideal for use in a wide range of industrial applications, including construction, automotive, and machinery assembly, where secure fastening is paramount. Their robust construction and adherence to recognised standards make them a dependable choice for engineers and maintenance professionals seeking durable fastening solutions.
