Spring Washers – Zinc
Zinc spring washers are designed to prevent nuts and bolts from loosening by applying tension within the fixing assembly.
About Zinc Spring Washers
Zinc spring washers are designed to help prevent nuts and bolts from loosening due to vibration or movement. Their split design allows the washer to apply tension when compressed, helping maintain pressure within the fixing assembly.
These washers are commonly used in mechanical assemblies, structural fixings and general construction where maintaining bolt tension is important.
How Spring Washers Work
A spring washer works by applying a small amount of tension between the bolt head or nut and the surface being fixed. When tightened, the split washer compresses slightly and helps resist loosening caused by vibration or movement.
This makes spring washers useful in applications where bolts may gradually loosen over time.
Typical Applications
- Preventing nuts and bolts from loosening
- Mechanical assemblies
- Machinery and equipment fixings
- Structural bolt connections
- General engineering and construction
Available Spring Washer Sizes
Spring washers are available in a range of metric sizes to suit common bolt and screw diameters.
| Bolt Size | Typical Use |
|---|---|
| M4 | Light mechanical assemblies |
| M5 | Small fixings and equipment |
| M6 | General construction fixings |
| M8 | Structural and mechanical fixing |
| M10 | Heavy duty fixings |
| M12 | Structural and engineering assemblies |
Zinc Plated Finish
These spring washers are zinc plated (CR3) and passivated to provide light corrosion resistance. They are suitable for internal applications and environments with low humidity.
How do you use a spring washer?
A spring washer is placed under the nut or bolt head before tightening. When compressed, the washer applies tension which helps prevent the fixing from loosening.
Spring washers are typically used alongside flat washers such as Form A washers to help prevent loosening due to vibration.
