Overview
The Posi-Tech ANTC-3803-AK is a professional-grade toggle bolt assembly engineered for secure fastening in hollow wall applications. This 3/8×3″ zinc-plated unit combines a Phillips combo truss head screw with a spring-wing toggle, creating a two-part anchor system. The ANTC-3803-AK is widely used in drywall, wallboard, and masonry block installations where standard fastening methods prove insufficient.
