A spiral shafted one-piece helical anchor with an 18mm dome head suitable for insulated flat roofing applications. The anchors can be hammered in manually or by using a standard SDS hammer drill with a dedicated adapter.
The hardened cutting blades make the anchors quick and easy to use, with a self-tapping action providing a permanent, secure anchor.
The thermally-efficient spiral shaft has a much smaller cross sectional area than that of a solid shaft of equivalent diameter to minimise disturbance to the materials being used, reducing cold bridging potential and avoiding splitting or other damage.
ISF18 anchors can be used without the need for pre-drilling, are as easy to use as conventional nail fixings and provide a firmer fix with reduced effort.
