Kep Nut

KEP Nuts, also known as Washer Nuts or Hex Nuts with Captive Star Washers, combine a hexagonal nut with an attached external tooth lock washer. They are manufactured to ASTM, DIN, and ISO standards in carbon steel, stainless steel, or brass. The captive washer provides excellent locking action, resists loosening under vibration, and saves assembly time by eliminating a separate washer. Available in zinc plated, galvanized, stainless, brass, or black oxide finishes, they provide secure fastening with added corrosion resistance. They are widely used in electronics, appliances, automotive, and general sheet-metal applications where vibration resistance is important.
