Designed to combine fast and easy use with improved drive, the Performance Plus high performance wood screw is the latest innovation from fixings specialists Samac. It offers merchants a profitable, high performance line that is easy to stock, in packaging that will sell itself.

The new Samac Performance Plus Wood Screw is packed with engineered features from head to point, making it the ideal screw to use on site. The Performance Plus Wood Screw features a reinforced pozi drive head and includes 6 self-countersinking ribs on the underside which ensures a consistently neat, flush finish.  Also because every box comes with a free pozi bit this enables single handed operation, speeding up work on site and saving time and money. Specially-designed ribs above the thread will clear the channel, reduce torque and help prevent wood splitting.  The thread itself is partially serrated, giving the screw a combined sawing and cutting action for smooth and efficient driving while the type 17 cut point improves drive and reduces splitting.

Performance Plus is available in 3.5-6mm gauges and in 15 – 200mm lengths and is available in customary boxes and trade tubs for easy and eye-catching merchandising.
