Advantages
| - Unique design, invented and patented by pgb |
| - The Hapax tip eliminates the need for pre-drilling, reduces the risk of splitting the wood and allows small edge and spacing distances |
| - Energy-saving, less stressful work and low insertion moment |
Applications
| - For wood-to-wood connections in general carpentry, interior and furniture construction and wood constructions |
| - For metal-to-wood connections. The full thread allows high screw pull-out force in connections designed for tensile forces |
| The triple thread point ensures that the screw quickly grips the wood and is powerfully screwed in. The specially shaped milling ribs under the head smoothly sink into the wood and stop on metal without damaging the surface. |
| The Hapax screws are ETA assessed wood screws. The BlueTop coating offers a better resistance to corrosion in a neutral salt spray test than conventional zinc plating. This makes the screw ideal for use in open constructions without direct exposure to the weather. |
