Welcome to Expodar! Fasteners are consumed throughout the world at an amazing rate. Each Boeing 747 has more than 2.5 million screws, and as science and technology advance, so does the demand for threaded fastener manufacturers. To stay quick, effective, and ahead of the curve, screw makers' processes are continually evolving, yet at their heart, little has changed over the past 300 years. It is possible to create screws with countless variations, including specialised head and drive styles, fine or coarse pitches, right- or left-handed ropes, flat tips, or gimlet points, to mention a few. As diverse as screws themselves, typical manufacturing steps might take many different forms. The production of fasteners can, however, generally be divided into two categories in the modern world.
