Keps External Tooth Hex Locknut Clear Zinc Cr3 Plating

The Keps external tooth hex all metal locknut with clear zinc Cr3 plating is a versatile, time-saving fastener designed for secure, vibration-resistant assembly in a wide range of industrial and commercial applications. Commonly known as a K-lock nut, this unique locknut features an integrated external tooth lock washer that’s permanently attached to the nut body, providing one-piece locking convenience that speeds up assembly while improving holding power.

The external teeth bite into the mating surface, locking the nut in place and resisting loosening from vibration or motion. This makes Keps nuts ideal for light to medium-duty applications such as appliances, automotive interiors, HVAC systems, metal enclosures, furniture, and electrical panels. They're a go-to solution for assembly lines and repetitive fastening tasks where efficiency and reliability are essential.

Manufactured from durable steel and finished with clear zinc Cr3 plating, these locknuts offer corrosion resistance in indoor and moderately exposed environments. The Cr3 (trivalent chromium) coating meets RoHS compliance standards, offering a more environmentally friendly finish compared to older hexavalent coatings, without compromising performance.
