NBK America LLC Datasheets for Screws

A screw is a wide-encompassing type of hardware fastener that attributes its mechanical capabilities to the helical groove that extends around the circumference of the device's shank. These threads provide the friction and traction that serves a screw's purpose: to assemble or position two workpieces in relation to each other. While used synonymously, screws and bolts are not mechanical clones.
