Spacers and standoffs are small hardware components used to create space between parts in industrial, electronic, and commercial assemblies. While they may look similar, they serve different purposes depending on the application.
What Are Spacers?
Spacers are unthreaded components used to maintain distance between two parts. They help improve alignment, reduce vibration, and prevent damage from over-tightening.
Common applications include:
- Electronics
- Industrial equipment
- Architectural hardware
- Display systems
What Are Standoffs?
Standoffs are threaded components that create space while also allowing parts to be securely mounted together.
They are commonly used for:
- PCB mounting
- Electronics enclosures
- Control panels
- Industrial assemblies
Spacer vs. Standoff
The main difference is threading.
| Spacer | Standoff |
| Unthreaded | Threaded |
| Used for spacing only | Used for spacing and mounting |
Common Materials
Spacers and standoffs are commonly made from:
- Aluminum
- Stainless steel
- Brass
- Nylon or plastic
Aluminum is especially popular because it is lightweight, durable, and corrosion-resistant.
Male vs. Female Standoffs
Male Standoffs
Have external threads on one end and internal threads on the other.
Female Standoffs
Contain internal threads on both ends.
The right choice depends on how the assembly is mounted.
Threaded vs. Unthreaded
- Threaded components provide secure fastening and support.
- Unthreaded components are mainly used for spacing and alignment.
Electronics Applications
Spacers and standoffs are widely used in electronics to:
- Mount circuit boards
- Improve airflow
- Prevent electrical shorts
- Support enclosures
Industrial Applications
Industrial uses include:
- Machine assemblies
- Architectural displays
- Signage hardware
- Retail fixtures
- Automation systems
Benefits
Using the right spacer or standoff helps:
- Improve alignment
- Reduce vibration
- Increase durability
- Improve assembly appearance
- Simplify maintenance
How to Choose the Right One
When selecting spacers or standoffs, consider:
- Material
- Size and tolerance
- Load requirements
- Thread type
- Environmental exposure
Custom machining may be required for specialized applications.
Common Mistakes
Avoid:
- Using the wrong material
- Choosing incorrect thread sizes
- Ignoring load requirements
- Overlooking corrosion resistance
FAQs
What is the difference between a spacer and a standoff?
A spacer is unthreaded, while a standoff includes threading for mounting.
What material is best?
Aluminum is commonly used for its strength, lightweight properties, and corrosion resistance.
Are standoffs used in electronics?
Yes. They are commonly used to mount PCBs and electronic components.
