Jam Nuts, or thin nuts, are low-profile fasteners designed to be tightened against another nut to lock it in place. Their compact size makes them suitable for applications with space constraints. When used in conjunction with a standard nut, jam nuts provide an additional locking mechanism, preventing loosening without the need for a lock washer. This makes them ideal for use in adjusting screws, threaded rods, and other mechanical assemblies where precise adjustments and secure locking are necessary. Jam nuts are a reliable solution for secondary locking in various industrial and construction settings.
