Welcome to Expodar. The world ingests fasteners at a fantastic rate. Over 2.5 million screws go into each Boeing 747, and as science and technology burgeons, so too makes the world’s need for threaded fasteners. The manufacturer’s procedure for screws constantly evolves to stay fast, efficient, and ahead of the curve, but at its core, screw manufacturers have varied little over the past 300 years. Screws can be developed with innumerable permutations, including specialist head and drive styles, fine pitches, coarse pitches, right or left-handed ropes, and flat tips or gimlet points, to name but a few. Typical steps in the manufacturing procedures can be as varied as the screws themselves. Still, in the modern world, fastener suppliers’ manufacture typically can be broken into two methods which differ in the machining utilized to form the threads: thread rolled screws and thread cut screws.
