The KUPO KS-177 is a set of five hexagon nylon locking nuts for 1/4"-20 threaded hardware. The nylon insert adds resistance against loosening, making it useful on small accessories that are moved, adjusted, or serviced often.
Why It Matters
Small camera and accessory hardware can loosen faster than crews expect, especially when gear is packed, rebuilt, and handled every day. KS-177 gives 1/4"-20 assemblies a compact locking nut option for maintenance drawers and field repair kits.
