Castle Nut Supplier Dubai

Castle Nuts, also known as Slotted Nuts, are hexagonal nuts with slots cut into one end for use with a cotter pin. They are manufactured to ASTM, DIN, and ISO standards in carbon steel, alloy steel, stainless steel, or brass. The cotter pin passes through the nut slots and a drilled bolt hole, ensuring secure locking against vibration and loosening. Available in zinc plated, galvanized, stainless, or brass finishes, they provide durability and reliability in critical assemblies. They are widely used in automotive axles, machinery, aerospace, railways, and heavy equipment where secure locking is essential.
