  • Assembly Screws & SEMS Screws
    Assembly Screws & SEMS Screws

    SEMS combines two normally seperate parts-typically a screw and a washer- into one permanently pre-assembled cost saving component. Washers are hel in place under the screw head by the rolled threads; they will not fall off and are free to rotate. Assembly screws were specially designed for assembly and installation of cabinets or other types of box construction. These unique fasteners act like steel dowels to form strong, stiff butt joints. The screws feature a large shoulder under the head to lock the screw into the wood and prevent pulling through into softer materials. These screws can be removed and reinstalled several times without loss of holding power.
