These Forgefix Cladding Nails are a universally popular fixing nail with a hardwearing polyamide head for increased durabililty when hammering home. Annular rings on the shank increase holding power. The large plastic top distributes the load underneath the head, preventing deformation and splitting on the cladding applications. The Nails are made of stainless steel, which offers excellent resistance to corrosion. 2.1 Gauge.Colour: White or Brown. Stainless Steel does not corrode, rust or stain with water as ordinary steel does, but despite the name it is not fully stain-proof, most notably under low oxygen, high salinity, or poor circulation environments. Stainless steel is used where both the properties of steel and resistance to corrosion are required.Polytop Pin Brown Stainless Steel 40mm Box 250
