Brass Fastener Screws
- Brass, Galvanized Steel, Stainless Steel A2, Stainless Steel A4
- Used for both interior and exterior work.
- To hold objects together and to position objects.
- Precision Screws for controlling motion rather than fastening.
- For critical high-tensile-strength applications, low-grade screws may fail, resulting in damage or injury.
- Available with large and fine bush and head.
- Screws are made with a concealed, small, cross, cylindrical, hemispherical and semi-hollow head.
- Screw heads keep the screw from being driven deeper than the length of the screw and to provide a bearing surface.
- Most Versatile and useful types of fasteners, Available in multiple sizes and styles.
- Threaded Screws either have a tapered shank or a non-tapered shank.
- For most screws, a coating, such as electroplating with zinc (galvanizing) or applying black oxide, is applied to prevent corrosion.
- The Screw Threads are usually produced via thread rolling, however some are cut.
- Three Steps in manufacturing Screws: Heading, Thread Rolling and Coating.
- Screws with tapered shanks are designed to either be driven into a substrate directly or into a pilot hole in a substrate.
- Screws with a non-tapered shank are designed to mate with a nut or to be driven into a tapped hole.
