What Are Threaded Inserts for Wood?

Threaded inserts for wood are specialized fasteners designed to create strong, reusable threads in wooden materials. These inserts allow bolts and screws to be securely anchored in wood, preventing stripping and ensuring long-term stability in applications requiring repeated assembly and disassembly.

Specifications of Threaded Inserts for Wood

1. Material Options

• Brass (CZ121/C36000) – Excellent machinability and corrosion resistance.
• Stainless Steel (304/316) – High strength and durability for industrial applications.
• Zinc Alloy – Cost-effective and suitable for general woodworking projects.

2. Surface Treatment

• Nickel Plating – Enhances wear resistance and provides a smooth finish.
• Zinc Coating – Protects against rust and environmental damage.
• PTFE Coating – Reduces friction for easier installation.

3. Common Specifications

• Thread Sizes – M4–M12 (metric), #6–1/2″ (UNC/UNF).
• Head Types – Flanged, hex drive, or countersunk.
• Installation Methods – Press-fit, self-tapping, or screw-in.
