High performance wood and chipboard screws.
The new range of Ulti-Mate screw has the very latest Recess and Thread Design Technology. One of the benefits of 'Stick-Fit' is the between bit and screw recess allows you to use one hand which makes work easier and safer. Ulti-Mate screws have Self-Countersinking ribs and the Thicker, Stronger Shank holds better in wall plugs. The advantages of the deep thread is that you can control the drive, it reduces stripping and you have a better hold. The new thread, with its waxed coating allows for a quick start in both natural and artificial woods. The screw has a great Golden Zinc finish which not only hardens the screw but makes for a top finish.
