Keps Nuts: The Secure Fastening Solution with Built-In Locking<\/strong><\/h1>\n

What Are Keps Nuts?<\/strong><\/h2>\n

Keps nuts (also called K-lock nuts or washer nuts) are a specialized type of hex nut with an attached free-spinning external tooth lock washer. The name “Keps” comes from the brand “Kepspeed,” which originally popularized this design. The integrated washer provides a locking function that prevents loosening due to vibration, making these nuts ideal for applications where secure fastening is critical.<\/p>\n

Unlike standard nuts, Keps nuts eliminate the need for a separate washer, speeding up assembly while maintaining vibration resistance. The washer’s teeth bite into the mating surface, creating friction that resists rotation. These nuts are commonly used in automotive, electronics, machinery, and other industries where vibration or movement could compromise fastener integrity.<\/p>\n
