hexagonal locknut / nickel-plated brass
The Precision Machined Nuts are designed for a wide set of applications requiring light loads. They are designed with a small hex size to allow work efficiency on narrow wrenching areas. Some of the designs include machine screw, hex, jam, cap, thumb nuts, and panel. Each of them differ in dimensions, finishes, and material compositions. The thread and the wrench size distance should be compatible for the nut pattern to work. They are readily available and are free from rough projections.
