Product Description

Still widely used in computers and electronic equipment to separate circuit boards for airflow and allow clearance for installed components. As these come in a wide array of sizes and threads, nearly every industry has used them as thread adapters, spacers, connectors and other unique applications. The hex shape allows for greater torquing as the flat sides allow for wrench tightening. Steel is inexpensive, easy to achieve finer surface quality requirements and provides relatively high strength properties. Multiple plating options are available to increase the material's corrosion resistance and alter its appearance.
