The two patented slots (25mm and above) allow the screw to work closer to the edge without splitting, and the ribs and tucks under the head enable the screw to sit flush and tight without surface damage.
The 20º needle point gives the ability to penetrate almost all timbers without a pilot hole and the sharp, wide deep thread gives up to 40% less driving resistance and easy penetration.
The Yellow Tropicalized coating gives superior corrosion resistance (compared to a standard BZP coating).
The deep reinforced countersunk head recess allows the best possible fit to the driver bit, reducing “cam out” and providing extra strength at the junction between shank and head.
6.0 X 40, 6.0 X 50 come in boxes of 200 screws, the reminding sizes come in boxes of 100 screws.
