Our fully Galvanised Staples are perfect for fixing wire fencing and straining wire onto wooden posts. These "U" shaped staples are designed to be hammered directly into the wood, and will result in a strong, secure fixing. We recommend that our 40mm staples are used with with medium to heavy-weight welded mesh and fencing. The staples are galvanised to slow down the process of rusting and corrosion meaning they last longer then normal staples.
