Jackoboard TileBacker Galvanised Fixing Washers (pack of 100)

These TileBacker Galvanised Fixing Washers will come in very handy when you're fixing Jackoboards into wooden joists, or when you're fixing boards together when sculpting structures in your wet room. Generally, galvanised wood screws are used with these washers. The washers stop the screws from collapsing the face of the Jackoboards, which would spoil the water-resistant qualities. You get 100 in this pack.
