We have a vast range of spacers designed for use in the Circuit Board. These spacers are available in Round & Hex shapes. A standoff is used in mechanics and electronics to separate two parts from one another. Standoffs can be many shapes and sizes and made of many different materials. Insulating standoffs keeps two parts from touching each other, thereby preventing an electronic short. Cable thumb screws are often screwed into standoffs on the back of computers. Standoff sizes are usually measured by the Unified Thread Standard. Size 4-40 is used to secure cables to external computer ports and size 6-32 is used for motherboard mounts. However the same are also available in metric & white worth threads.
