The K-cap nut, also known as a K-nut or K-lock nut, is a fastener with a unique design. It combines a standard nut with an integrated free-spinning washer.The K-Cap Nut consists of a hexagonal nut and an external washer with a series of small teeth or serrations located on the inner surface of the washer. These teeth are designed to bite into the mating surfaces and provide resistance to vibration loosening. When tightened, the teeth on the washer become embedded in the material, creating a lock that helps prevent the nut from loosening.

Carbon Steel: Typically used for general applications. Stainless Steel: For environments where corrosion resistance is required. Alloy Steels: Used in applications requiring high strength or high temperature resistance.

Advantage:

ANTI-LOOSE PERFORMANCE: The tooth or serrated design on the washer provides an additional locking feature to prevent loosening due to vibration or external force. EASY TO INSTALL: K-cap nuts can be easily installed and removed for easy maintenance. MATERIAL VERSATILITY: K-cap nuts can be made from a variety of materials including steel, stainless steel, brass and nylon to suit different applications and corrosion resistance needs. Compact: The compact design of the K-Cap Nut makes it suitable for applications where space is limited.

Scope of Application

K-cap nuts are widely used where secure connections are required and where there is a risk of loosening due to vibration or dynamic loads. They are commonly used in automotive, industrial and other mechanical applications.
