SM Through Bolt Anchor:M20 x 220 (ETA Approved)

The SM Through Bolt Anchor is a structural fastening solution designed to secure heavy loads directly through structural elements into a base material. Manufactured to meet rigorous engineering standards, this anchor system has received European Technical Assessment (ETA) approval, validating its performance and safety for critical applications. This certification is a key differentiator for buyers requiring verified load-bearing capacity in seismic or high-stress environments, ensuring compliance with current building regulations. The M20 designation indicates a nominal thread diameter of 20 millimeters, while the 220 millimeter length specifies the embedment depth required for the specific installation scenario. Buyers should select this size and grade based on the structural load calculations and the thickness of the concrete or masonry substrate to ensure adequate anchor engagement and pull-out resistance.
