85mm Insofast ISF18A Insulated Plasterboard Fixings (pack of 400) - SDS tool not included.

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.

• Fire-proof mechanical fixing
• Helical shaft minimizes heat loss through cold bridging
• Countersunk head prevents tearing
• Dished head retains filler
• Dependable performance
• Suitable for replacing or complementing dot and dab installation
• Works with a wide range of construction materials
• Efficiently fixes panels to lightweight blocks without pre-drilling

• The anchor can be directly driven into aircrete (Celcon, Thermalite, etc.) and softwood timber
• Use a 5mm pilot hole for brick, concrete block, and hardwood
• Compatible with all types of insulated drywall boards
• Dot and dab adhesive - 3 per board, or without it 12 per board, to ensure stability of the boards in the event of a fire.
• Cold bridging minimized due to thermally efficient spiral shaft
• Fully countersunk head reduces tearing and indentation into the gyproc layer
