    Description
    Hex Bolts
    Hex bolts, commonly called hex head cap screws, are bolts that contain a hexagonal head, smooth shank, and threads. The length of the threads ranges from 1" to 6", depending on the diameter and length of the bolt. The approximate thread length for each specific bolt can be found under the "Additional Info" section. The length of hex bolts is measured from the bottom of the hex head to the end of the threads. In addition to hex bolts, we also offer tap bolts, which are hex bolts that are fully threaded.

    Our inventory of hex bolts includes a variety of lengths and diameters, many of which are available in either stainless steel or hot dipped galvanized finish. If you don't see the size, grade, or finish you are looking for, please call us at 1.800.677.4710.
