# Hardware

## #10 Hardware Basics

The REV ION build system uses[ #10 Hardware ](https://www.revrobotics.com/ion/hardware-tools/)to connect, or fasten, brackets and structure together on a robot. Different applications require different length screws. When attaching a bracket to extrusion, shorter screws are generally required. Use longer screws to connect Control System components and other thicker materials.

## Standoffs

Aluminum threaded standoffs [(Product Family Page) ](https://www.revrobotics.com/10-32-Standoffs/)are an easy way to assemble structural components like plates, brackets and tubes. Tapped on each end with a #10-32 thread and a 3/8in flat to flat dimension similar to a #10-32 nut.
