Thinking about building a deck in the near future? Looking for the perfect screw? We sell treated pine screws that are specifically made for use with this type of wood, and as with all of the Robertson Screws range, they feature the ‘square drive system’. This system had proved to be much easier to use than a regular drive system, as the square design means it is much harder for the driver to jump out when drilling.
When building a deck, or anything outside for that matter, you want screws that are resistant to rust – otherwise you could be replacing them much sooner then you expected. These particular screws are coated in MAGNIGARD, a finish that ensures excellent corrosion resistance. In addition, they feature sharp thread angles and points which allow them to penetrate the wood quite easily.
Origin of the Robertson square drive screws
The "Robertson" screws were invented in Canada by Peter Robertson in 1908. Due to patent restrictions they stayed in Canada for many years and became the standard screw in that country. They are now spreading rapidly through the US and other countries. It is a far superior system and we are sure you will agree “once you use them you don't want to use anything else”.
Not only is the drive system better than the conventional drives, the actual quality of the screws is superb. The screws are extremely strong and the square drive means the driver doesn't jump out and the screw does not break under heavy load.
