Kotwa M12 fi 18 L-120 Pipe Anchor with Adjustable Hinge S235JR Steel White Zinc

Product Overview

The Kotwa M12 fi 18 L-120 with adjustable hinge is a cylindrical pipe anchor designed for embedding into solid concrete. The anchor body features a narrowed section at the front with internal threading, providing a secure mounting point for a hinge. Made from S235JR steel and finished in white zinc galvanization, this anchor is commonly used by installers and contractors in commercial and industrial construction environments where reliable fixing to concrete is essential.

The key element distinguishing this SKU is its perimeter-profiled narrowing, which serves as a material accumulation point for bonding agent and enhances the mechanical integration with the substrate. This feature ensures a stable, durable installation while reducing the quantity of chemical anchor material required. The product is recommended for bulk procurement and use in large-scale concrete door frame assemblies, particularly in projects needing adjustable hinges for post-installation alignment.
