Hex nuts are used to prevent shear movement and tension when adhering facing materials together with machine bolts. Hex nuts are commonly used in wood to wood, wood to metal, and metal to metal applications. The black phosphate finish combines moderate corrosion resistance with aesthetics to match surrounding hardware. Be sure to pre-drill any holes and to use bolts that are a similar grade and finish. Parts feature a free-spinning flat washer that tightens as the nut is installed.
