    Description
    Round Lock Washers
    Lock washers are split round washers that have a hole in the center. They are typically used where loosening from vibration is a concern and are often used in addition to flat washers. The washer size designates the diameter of hole in the center. Lock washers are used with bolts and washers of the same diameter, material, and finish.

    Our inventory of lock washers includes a variety of sizes, 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.
