Hexagonal nuts, also known as hex nuts, are a fundamental component in fastening systems across various industries, including MRO and automation. These six-sided nuts are designed to be paired with bolts or screws to securely join parts together, offering high torque resistance and durability. Common types include standard hex nuts, lock nuts (with nylon inserts to prevent loosening), and flange nuts (with built-in washers for better load distribution). Available in materials like stainless steel, brass, and zinc-plated steel, they cater to diverse environmental and load-bearing requirements. Hex nuts are essential in machinery assembly, structural frameworks, and equipment maintenance, ensuring reliable and long-lasting connections.
