Metric Class 8 External Tooth Keps Hex Locknut, Zinc Cr+3
Metric Class 8 External Tooth Keps Hex Locknuts Zinc Cr+3 are high-strength, self-locking fasteners designed for efficient assembly and reliable vibration resistance. These nuts feature an integrated external tooth lock washer that bites into the mating surface to prevent loosening under dynamic loads. Manufactured to property class 8 specifications, these Keps locknuts combine the strength of a standard hex nut with the locking reliability of a toothed washer. The Zinc Cr+3 (trivalent chrome) plating provides durable corrosion resistance and a clean silver-blue finish while offering an environmentally friendly alternative to traditional hexavalent coatings.
Engineered for performance and convenience, Class 8 External Tooth Keps Hex Locknuts with Zinc Cr+3 finish are ideal for use in machinery, appliances, electronics, and general industrial applications where vibration resistance and corrosion protection are critical. The pre-attached external tooth washer reduces assembly time and ensures consistent locking torque. The Cr+3 zinc plating delivers excellent rust resistance and a smooth finish for easy installation, making these locknuts a reliable choice for medium to high-strength fastening applications.
