The WERCS AnkaScrew Screw-In Anchor is a totally removable, medium duty, rotation se - TTIng, thread forming anchor, ideal for either temporary or permanent anchoring into substrates such as concrete, brick, hollow brick or block. The WERCS AnkaScrew is particularly well suited to close-to-edge or close-to-anchor fixing as it does not expand and burst the surrounding substrate. - High thread engagement increases clamp force and holding capacity over a wide range of loading. - The WERCS AnkaScrew is ideal for close-to-edge and close-to-anchor installation as its self-tapping, rotation se - TTIng method of installation is subject to low expansion pressure, therefore does not burst the substrate. - For concrete, brick & block (solid & hollow). The WERCS AnkaScrew thread design provides clearance for rapid removal of material and reduces jamming. - The WERCS AnkaScrew is 100% removable. - The WERCS AnkaScrew is both fast and easy to install as it simply screws into a pre-drilled hole. - The WERCS AnkaScrew is even faster and easier to remove. It simply screws out leaving an empty hole with no protruding metal parts to grind off. - Available in galvanised for exterior applications. - Suitable for installation with impact wrenches. - Specifications:Material: High Carbon Steel - Corrosion Protection: Zinc Plated - Head Styles: Flanged Hex - Fixing Method: Through FixtureSeTTIng Method: Rotation - Anchoring Method: Thread Forming - Drilled Hole Diameters: 12mm - Anchor Lengths: 75mm - Maximum Fixture Thickness: 15mm - Indicative Working Loads in 32MPa Concrete: Max Tensile 4.1k - N -14.4k - N | Max Shear 4.5k - N - 16.7k - NSubstrates: Concrete, Solid Brick, Solid Block, Hollow Block, Hollow Slab, Hollow Brick
