Dual-thread hanger bolts (also known as wood-to-metal dowel screws) are specialised headless fasteners designed to connect timber structures directly to metal components. They feature a self-tapping coarse wood thread on one end and a standard metric machine thread on the other.

Key Specifications & Sizing:

These bolts are typically made from high-strength carbon steel coated in Bright Zinc Plating (BZP). The zinc layer provides excellent indoor corrosion resistance, making them ideal for furniture manufacturing, joinery, and staging.
