hexnut
A hexnut, also known as a hex nut, is a fundamental fastening component characterized by its distinctive six-sided shape. This geometric design enables efficient torque application using standard wrenches and sockets, making it one of the most widely used fasteners in industrial, construction, and DIY applications. The hexagonal shape provides six points of contact, ensuring superior grip and more even distribution of force during tightening and loosening operations. Manufactured from various materials including steel, stainless steel, brass, and nylon, hexnuts feature internal threading that corresponds to specific bolt or screw sizes. The threading can be either coarse or fine, depending on the application requirements. Modern hexnuts often incorporate additional features such as nylon inserts for vibration resistance, self-locking mechanisms, or corrosion-resistant coatings. They are produced according to standardized specifications, ensuring consistency and interchangeability across different manufacturers and applications. The versatility of hexnuts makes them essential in automotive assembly, machinery construction, structural engineering, and countless other industrial applications.
