The M12 x 110mm Resin Chem Hammer‑in Capsule is a glass, two‑part chemical anchoring capsule designed to secure M12 threaded rods or studs into pre‑drilled concrete and masonry. Its primary use is to create a bonded mechanical and chemical connection where expansion anchors are unsuitable or where higher pull‑out and shear capacities are required, for example fixing balustrades, heavy rails, façade brackets and structural connections.

The capsule contains a pre‑measured, two‑component vinylester resin (styrene‑free formulation) and a hardener held within a sealed glass ampoule. The product is intended to be used with M12 metric coarse threaded rod to ISO 261/262 and compatible with common property classes such as 8.8 carbon steel and stainless grades A2 (304) and A4 (316) depending on corrosion requirements. Installation is by hammer‑in: insert the capsule into a clean, drilled hole (hole diameter matched to the M12 anchor), then push the threaded rod into the capsule to break the glass and mix the resin; curing time is temperature dependent and should follow the manufacturer’s guidance.

Where relevant, designers should refer to recognised anchor design guidance such as the European Technical Assessment/ETAG procedures and national codes (for example, EAD/ETA documentation and BS EN guidance for anchors in concrete). The resin anchor system offers effective bonding in both cracked and uncracked concrete, and when used with stainless rod provides enhanced corrosion resistance for external or marine environments.

Typical applications include construction and civil engineering, glazing and balustrade fixing, mechanical and plant anchoring, and specialist restoration work where vibration or dynamic loads are present. Key benefits are accurate dosing (no on‑site mixing), a high‑strength load transfer between rod and base material, good chemical isolation of the rod within the hole, and broad compatibility with standard M12 threaded components and grades.
