Jam Nut

Jam nuts, also known as half-height hex nuts, are a type of lock nut designed to be thinner than standard hex nuts. Their reduced height allows them to be used in applications where a full-sized nut would be too bulky or where space is limited. These versatile fasteners are commonly used as a second nut threaded against the first to prevent it from loosening due to vibration, a technique often referred to as "jamming." This makes them a reliable choice for securing components in various assemblies.

Our collection features a wide range of jam nuts in different materials, sizes, and finishes. Whether you need a standard hex nut, a high-strength locking nut, or even specialized weld nuts, you can find the right product here. They are used in countless applications, from machinery and automotive repair to construction and DIY projects. By providing a secure and reliable hold, these screw nuts are an essential component for ensuring the longevity and safety of your mechanical connections.
