All Metal Lock Nuts

All-metal lock nuts, also known as prevailing torque nuts or stiff nuts, are a type of fastener designed to prevent loosening due to vibration or other external forces. Unlike standard nuts, which rely on friction between the threads of the nut and the bolt to stay in place, all-metal lock nuts incorporate a design feature that increases resistance to rotation. This added resistance helps maintain a secure connection between the nut and bolt.

All-metal lock nuts are commonly used in applications where maintaining a secure and vibration-resistant connection is critical, such as automotive, aerospace, machinery, and construction industries. They offer a reliable solution for preventing unintended nut rotation and potential loosening of fasteners.
