Jam nuts are an important component in mechanical fastening, providing a secure way to prevent loosening in applications where vibration or movement occurs. This article provides a detailed look at jam nuts, including their purpose, sizes, torque specifications, and how they compare to other types of nuts. What is a Jam Nut? A jam nut, also known as a thin nut, is a type of fastener that is about half the height of a standard finish nut. While the circumference and thread sizes are the same as a standard nut, its reduced height makes it suitable for applications where spac......
