Masonry Screw Anchors — Direct-Fix Concrete & Masonry Screws
Masonry screw anchors thread directly into a pre-drilled pilot hole in concrete, brick, and block — providing a fast, reliable fastening point without a separate expansion anchor component. AIMS Industrial sells masonry screw anchors in hex head and countersunk profiles, zinc-plated and stainless steel, for direct fixing of structural brackets, service supports, and mechanical equipment to concrete and masonry substrates.
Masonry Screw Anchors We Stock
- Hex Head Masonry Screws: Hex head masonry screw anchors for structural bracket, post base, and fixture fastening into concrete and brick — the hex head allows installation with a socket or spanner and provides visual verification that the anchor is fully seated.
- Countersunk Masonry Screws: Countersunk masonry screw anchors for flush surface mounting where a protruding hex head is not acceptable — floor rails, track mounting, and architectural fixings.
- Zinc-Plated Masonry Screws: Zinc-plated masonry screws for interior and protected structural fixing — appropriate for indoor construction, interior fit-out, and industrial buildings not subject to direct water exposure.
- Stainless Steel Masonry Screws: 316 stainless steel masonry screw anchors for coastal, marine, food processing, and outdoor applications where zinc-plated anchors would corrode. Required for fixing into concrete within marine splash zones and NATA corrosion category C3 and above.
Masonry Screw Anchor Selection & Installation Guide
- Pilot Hole Diameter: Masonry screws require a specific pilot hole diameter in the substrate — typically the screw major diameter minus 1mm. An oversized pilot hole reduces thread engagement and anchor capacity; undersized pilot holes cause screw installation difficulty or breakage.
- Minimum Edge and Spacing Distances: AS 3600 and anchor manufacturer datasheets specify minimum edge distance and anchor spacing for concrete and masonry substrates — these must be respected to achieve the rated anchor capacity. Anchors installed too close to edges or other anchors have reduced pullout and shear capacity.
- Substrate Condition: Masonry screw anchors require a minimum compressive strength substrate (typically 20–25 MPa for concrete) and must not be installed in cracked concrete or deteriorated masonry. Check the substrate condition and consult the manufacturer's technical data sheet for critical applications.
