What Is a Jam Nut?
A jam nut is a specialized tool designed to secure bolts and nuts, preventing them from loosening due to vibrations or impacts.
There are primarily two types of jam nuts: hex jam nuts and round jam nuts. These nuts are commonly used in various industries, including manufacturing, construction, and automotive maintenance. The mechanism of a jam nut involves its threads interlocking with the bolt’s threads, ensuring the bolt stays firmly in place. When a jam nut is installed and tightened, it effectively safeguards the bolt against loosening from vibrations and impacts.
Notable features of jam nuts include their ability to provide secure fastening, ease of use, and compatibility with different bolt sizes. Correct usage involves selecting a jam nut that matches the bolt size and ensuring it is properly tightened for optimal effectiveness.
