Designed and developed specifically for wood-to-metal. Pro Bolzen screws are self-drilling, self-tapping wood-to-metal fixings.

Pro Bolzen screws come in a 5.5mm diameter and a range of lengths, from 60mm up to 200mm. The 200mm fixing will allow you to fix timber – with a maximum thickness of 165mm– to steel with a maximum thickness of 12mm. This means Pro Bolzen screws can adapt to almost any structural or manufacturing application.
