Timber decking screw. Hobson Engineering have developed a superior timber decking screw. The TDXÂ® screw is a new design that enables a combination of the features that the market requires in a screw.
These features include; 304/A2 stainless steel for corrosion resistance; a special point, cut and thread so that pre drilling is not required into most hardwood to save time and money; a trim head for a neat finish; a No.1 square drive so the bit will not slip and a new type of square thread for greater holding power which prevents the deck from lifting.
