A fastening system for decking boards (16) includes a series of supports (14) which attach to a bearer (12). The supports define a central raised wall (24) and two planar portions (22) located either side of the wall. In the centre of the wall there is a cylindrical recess (30) which receives a stem (52) depending from a generally semi-circular washer (18). The stem (52) can rotate in the recess. The decking boards define slots which run along both sides of the board. In use, a first pair of supports is located on a bearer (12) and a first board is supported on the planar portions (22) of the supports, above the bearer. The washer is rotated so that one half of the semi-circular top (50) of one washer extends into the slot in the side of the decking board. The washer is then fixed in place by a screw which extends through the stem into the support and into the bearer. A board is then located adjacent the first board on the support and a further support is slipped under the free side of the board and the washer in the further support is rotated and locked in place with a screw. The heads of the screws are visible between the boards and can be accessed and partially unscrewed to allow rotation of the washer to allow the removal of individual or multiple boards. |
