What Are Support Washers?
Support washers are specialised mechanical components designed to reinforce fastening points in materials prone to deformation or failure. They provide a stable surface area that distributes load more evenly across soft, brittle, or non-metallic materials.
Advantages of Using Support Washers
When engineered and applied correctly, support washers offer multiple mechanical and operational advantages across industries.
1. Material Protection
Support washers protect vulnerable surfaces like rubber, plastic, cork, or composite panels from being crushed, cracked, or distorted under bolt or screw pressure.
2. Improved Load Distribution
By spreading force over a wider contact area, support washers reduce the risk of material failure at fastening points. This improves long-term structural integrity.
3. Enhanced Seal Performance
In systems using soft gaskets, support washers ensure even compression, which preserves the effectiveness of the seal and reduces the chance of leaks.
4. Increased Assembly Longevity
Support washers improve the durability of bolted joints, reducing the frequency of repairs or replacements in high-load or high-vibration environments.
5. Versatility Across Applications
Their mechanical versatility makes support washers suitable for plumbing, electrical systems, automotive components, marine equipment, aerospace structures, and general industrial use.
Key Applications of Support Washers
Support washers are used across a wide range of industries, where protecting soft or fragile materials is essential to maintaining structural performance and safety.

Issues Support Washers Solve
Choosing the right washer prevents a wide range of mechanical issues that can cause delays, damage, or system failure.
Without Support Washers:
- Soft materials such as rubber or plastic become damaged or pulled through fasteners.
- Gaskets can be displaced, resulting in seal failure and leaks.
- Bolted joints may loosen over time, requiring frequent maintenance.
- Cracking in brittle components can cause short circuits or breakdowns.
- Vibration can weaken joints and reduce performance.
- Corrosion from material mismatch leads to early failure.
With Support Washers:
- Fastening pressure is distributed evenly and safely.
- Gasket integrity is maintained over time.
- Joints remain tight and stable under vibration.
- Material-specific choices eliminate galvanic corrosion.
- Systems run reliably with reduced maintenance needs.
