85mm Insofast ISF18A Insulated Plasterboard Fixings (pack of 400)

85mm Staifix Insofast Anchor is a robust one-piece metal fastener designed to securely attach drywall and insulated plasterboard panels to walls. This fire-resistant anchor features a dish-profiled head, providing reliable mechanical fastening. Its fireproof construction adds an extra layer of safety, preventing dot and dab plasterboard from falling during emergency situations.

The self-tapping helical shank with work-hardened blades allows the anchor to penetrate a variety of masonry and timber substrates when used with a standard SDS hammer drill and compatible adapter.

Please note that the SDS tool is not included.
