Nuts are used to fasten machine threaded fasteners in through-hole applications, and available in a variety of styles, sizes, materials, and finishes. Choose anacorn nut when mating threads are exposed, or a hot dipped galvanized coupling nut with internal threads at both ends for joining studs and bolts. When your application has vibrations and torque, be sure to use a prevailing torque locknut or surface-bearing locknut to prevent your nut from loosening.
