Concrete Bolts

Concrete bolts, also known as masonry bolts, are heavy-duty fasteners designed to secure timber, steel, or structural components directly into concrete, masonry, or blockwork. Commonly used for fixing timber posts, handrails, fencing, machinery bases, shelving, structural supports, and outdoor furniture to concrete or masonry surfaces, they provide strong, reliable anchoring for permanent or load-bearing installations. Browse our range of concrete bolts, including zinc-plated and galvanised options, with variations in length, diameter, and head style such as hex and countersunk. Offering differences in holding strength, corrosion resistance, and suitability for indoor, outdoor, light, and heavy-duty applications, they meet the needs of DIYers, builders, carpenters, joiners, and trade contractors. Featuring threaded or expansion designs for secure grip in concrete and durable steel construction to help prevent bending during installation, our bolts ensure secure, professional, and long-lasting concrete fixings.
