The coil spring washer combined with a plain washer will ensure castors are securely attached to the castor board. Road cases are constantly loaded into the back of a truck and have to deal with a lot of vibrations on the road. So it is important that castors are installed securely using washers and coil springs.
We put together a list of hardware for use with swivel castors below for your convenience:
- 16X M8 Tee-Nuts
- 16X M8X35MM Bolts (when working with road case built with 9mm or 12mm plywood panels, and using 18mm plywood panel as castor board).
- 16X M8 Plain Washer
- 16X M8 Coil Spring Washer
Feel free to give us a call when you have any questions and don’t forget to share your finished road case to our Facebook for a 20 dollars credit to be applied to your next order. Happy building.
