SPA 07/08/09 High Strength Insulating Spacers
PSM SPA07, SPA08, and SPA09 spacers are high-strength insulating spacers combining acetal (a strong engineering plastic) with permanently retained brass inserts or studs. These spacers offer the benefits of plastic insulation together with enhanced mechanical durability from brass reinforcement.
Advantages
> Acetal spacers incorporating permanently retained brass inserts or studs
> High strength reusable threads
Materials Available
AB – Acetal with brass insert
Dimensions
Key Features
- High strength reusable threads thanks to brass inserts
- Good electrical insulation from the acetal body
- Lightweight compared to full-metal spacers
- Stable under normal temperature ranges
- Suitable for assemblies needing both mechanical strength and insulation
Common Applications
These insulating spacers are ideal in contexts where electrical isolation and mechanical strength both matter. Typical uses include:
- Mounting circuit boards or components where current leakage must be avoided
- Supporting panels in instrumentation and control systems
- Interfaces in assemblies where both insulation and secure fastening are required
- Environments where light weight is beneficial but structural integrity is not to be compromised
Insulating Spacers Selection Tips
- Match the spacer’s thread type and size to your screws or bolts
- Choose a spacer length that keeps adequate clearance between components
- Avoid over-tightening to protect the acetal body
- Consider environmental conditions (temperature, humidity) to ensure material performance

What are PSM SPA 07/08/09 High Strength Insulating Spacers?
What is the difference between SPA 07, SPA 08, and SPA 09?
SPA 07, SPA 08, and SPA 09 share the same acetal-with-brass-insert construction and AB material code but differ in thread configuration. SPA 07 is female-female (brass inserts at both ends, internally threaded), SPA 08 is male-female (one brass stud externally threaded, one brass insert internally threaded), and SPA 09 is male-male (brass studs externally threaded at both ends) — allowing engineers to select the correct thread interface for their specific assembly stack.
