The distance strip is particularly suitable for the visible fastening of decks， it acts as a spacer and enables movement between boards and substructure. At the same time， it supports air circulation underneath the deck; if this is not done， the result is rotting. The distance strip is made of hard plastic and is intended to prevent the stainless-steel screws from shearing off. Shearing is caused by swelling and shrinkage of the timber， or so-called warping. This warping is particularly pronounced in the boards transverse direction. The timber wants to take the screw with it， while the lower part of the screw remains securely fixed in the substructure. Since the density of hardwood and tropical wood means the timber is very hard， the screw has no chance of pressing itself into the timber during warping. When the screw breaks off under this strain， this is known as shearing. The distance strip was developed to prevent stainless-steel screws from shearing off. It provides a leeway of 0.51 in. between the substructure and the deck board， allowing the stainless-steel screws to move with the wood.
