Product Expert Notes
The Titen HD's big advantage is speed: no epoxy cure time and no torque-controlled expansion, so you can drill and drive in sequence. Match your hole diameter and embedment to Simpson Strong-Tie's published tables for the 3/8 in. size to achieve rated loads. For repeated installations or treated lumber contact, consider the mechanically galvanized THD variants instead of this zinc-plated box.
Always drill with proper eye and hearing protection and confirm embedment depth and load requirements against the manufacturer's evaluation report before relying on the anchor structurally.
