Concrete Bolts are heavy-duty fasteners designed to anchor directly into solid concrete surfaces. They cut or form threads into pre-drilled holes, providing strong holding power without the need for plugs. Manufactured to ASTM and DIN standards, they are available in various materials, grades, and protective coatings. Concrete bolts are easy to install, removable, and reusable for multiple fixing applications. They are widely used in structural anchoring, machinery installation, construction, and safety railings.
