PROSOCO Stitch-Tie Asymmetric 10 mm Helical Wall Tie – 50/Box

The PROSOCO Stitch-Tie Asymmetric 10 mm is a dual-diameter helical anchor designed to connect softer exterior masonry veneer to harder interior backup materials. Its smaller-diameter end embeds into the harder backup, while the 10 mm helical outer diameter engages the softer masonry veneer to provide optimum tension capacity across the connection. This asymmetric design is especially useful when the density or hardness of a concrete backup restricts the installation of a standard full-diameter helical tie. It allows the backup and veneer portions of the connection to use appropriately sized pilot holes, helping prevent the loss of anchorage capacity that can occur when the veneer pilot hole is oversized. Features & Benefits 10 mm helical outer diameter engages softer masonry veneer Smaller-diameter end embeds into harder backup materials Connects soft exterior masonry substrates to harder interior walls Dual-diameter design provides optimum tension capacity Self-taps directly into properly sized pilot holes Helical design provides continuous grip Installs with minimal disturbance to the existing facade Color-coded for quick identification and installation Installs using a rotary hammer and the appropriate setting tool Ideal where hard or dense backup material restricts standard helical-tie installation Installation Recommendation PROSOCO recommends completing an on-site mock-up before installation. The mock-up should be used to confirm whether the Stitch-Tie Asymmetric is appropriate and to establish the optimum pilot-hole diameter for both the veneer and backup materials. Required Installation Equipment Rotary hammer Appropriate PROSOCO setting tool Properly sized drill bits based on the approved mock-up
