AMK offers a great selection of bulk tapping screws with “SEMS” washers. Let’s learn about them … “SEMS” stands for “Screw and Washer Assembly”. The process requires a washer with an exact inside diameter, large enough to fit onto the screw blank before thread rolling and smaller than the major diameter so it will not slip off after thread rolling. Also, a special washer feed system called a “SEMS roller” is utilized to automate the installation of the washer. AMK goes all-out to facilitate the production of our bulk tapping screws. AMK stocks and supplies over 1 million SEMS washers to our manufacturers annually. We are very familiar with the intricacies of conical, conical tooth, external, internal/external, countersunk, finish and additional special types of SEMS washers.
Most AMK Products tapping screws are manufactured in USA.
