Wood Screw Information and Specifications. SCREW SIZING. The general size of a screw is given a number. As the number increases, so does the size of the entire screw , both head size and shaft size--but not length. Therefore, a #8 screw is about twice the size of a #4 screw , but may be the same length. Wake Up!-- This is important. Screws Information . Show all Screws Manufacturers A screw is a 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: Background History Raw Materials Design The Manufacturing Process Quality Control Where to Learn More Screws are part of a family of threaded fasteners that includes bolts and studs as well as specialized screws like carpenter's wood screws and the automotive cap screw. The threads (or grooves) can run right handed or left, tapered, straight, or parallel. There are two types of screws, machine and wood screws. Both are made of metal, however the machine screw has a constant diameter and joins with nuts while the wood screw is tapered and grips to the actual wood surface.

Screws are used to fasten materials by digging in and wedging into a material when turned, while the thread cuts grooves in the fastened material that may help pull fastened materials together and prevent pull-out. There are many screws for a variety of materials; heremonly fastened by screws include wood, sheet metal, and plastic.

Metric Machine Screw Diameter and Thread Chart Our printable 'lay-over' sizing chart for identifying metric machine screw diameter and thread pitch. For tapping power screw threads, best results are obtained using a vertical, lead screw set-up. This promotes good chip removal and coolant flow. The tap should be passed through the nut after tapping and not backed out by reversing rotation. The screw propeller, although it shares the name screw , works on very different physical principles from the above types of screw , and the information in this article is not applicable to it. Distance moved. The linear distance a screw shaft moves when it is rotated through an angle of degrees is:
