# Standoffs

Standoffs are rigid spacers with threaded ends or through-holes used to separate and support two parallel components at a fixed distance. They are commonly used in FRC to build compact, lightweight assemblies.

</div>## What They Do

Standoffs:

- Maintain a fixed distance between plates or components
- Provide structural support without adding bulky brackets
- Allow fasteners to pass through or thread into both ends
- Help keep assemblies rigid and aligned

</div>## Common Types

- **Threaded standoffs:** Threads on both ends for bolting into components
- **Through-hole standoffs:** Bolts pass through the entire length
- **Hex standoffs:** Easier to grip with a wrench during installation

</div>## Common Applications

- Electronics mounting plates
- Sensor and controller stacking
- Gearbox and mechanism spacing
- Lightweight structural supports between plates
- Compact multi-layer assemblies

</div>## Materials

- Aluminum (most common in FRC)
- Steel (higher strength, heavier)
- Plastic (light-duty or electrical isolation)

Aluminum is preferred for most mechanical applications due to its strength-to-weight ratio.

</div>## Best Practices

- Use the correct length to avoid preloading or flexing parts
- Ensure threads are fully engaged on both ends
- Avoid over-tightening, which can strip threads in softer materials
- Combine with washers when needed for surface protection

</div>## Key Idea

Standoffs create precise, rigid spacing between components, allowing FRC teams to build compact and organized assemblies while maintaining strength and alignment.
