Square Head Nut is a fastener with a square head that is often used in scenarios where space is limited or high torque is required. Its square design facilitates quick fixing with ordinary wrenches or open-ended tools, especially in tight environments where it has an operational advantage over hexagonal nuts. Mainly used in rail equipment, steel construction, agricultural machinery and other heavy-duty areas, through the square neck bolts with the formation of anti-rotation structure, can effectively resist severe vibration and shock loads. In the railroad track fastener system, the square head nut can ensure the long-term stability of the rail by using with the spring bar. Its thick square structure is also commonly used in the reinforcement of wooden structures, both high load bearing and easy to install, is an important basic fastening element in industrial equipment. |
