Concrete screws cut their own thread directly into a pre-drilled hole in concrete, with no expansion force on the substrate. That makes them usable at close edge distances and in thin sections where an expansion anchor would crack the concrete, and they can be removed and reinstalled.
Supplied in bulk to distributors, importers and hardware brands worldwide, including private-label packaging in the customer's own branding. Non-standard sizes and made-to-drawing variants are produced to order, with a material test certificate on every consignment.
