Chipboard Screws: Features, Types, and Usage Guide

Chipboard Screws: Features, Types, and Usage Guide

1. What is a Chipboard Screw?

A chipboard screw is a specially designed fastener with a sharp, deep-thread structure intended for securely joining particleboard, MDF, plywood, and other wood-based panels.

Compared to standard screws, its deeper and sharper threads provide a strong grip in porous wood surfaces.

2. Features of Chipboard Screws

Chipboard screws are among the most commonly used fasteners in the furniture industry.
Key features include:

• Sharp Thread Design: Easily penetrates wood panels and provides a tight grip.

• Self-Tapping Capability: Often does not require pre-drilling.

• Variety of Sizes: Available in diameters from 3.0 mm to 6.0 mm and lengths from 13 mm to 120 mm.

• Corrosion Resistance: Usually zinc-coated to resist moisture and rust.

• Flat or Countersunk Head: Allows for flush installation for a neat appearance.

3. Applications of Chipboard Screws

Chipboard screws are essential in furniture assembly and interior construction, commonly used in:

• Furniture Manufacturing: Cabinets, tables, chairs, bed frames, drawers, shelving systems

• Kitchen and Bathroom Cabinets: Stainless or galvanized screws for humid environments

• Panel Installation: Fastening MDF, particleboard, or plywood panels

• Door and Window Frames: Securing wooden frames

• Flooring and Wall Cladding: For wood or chipboard-based coverings

4. Types of Chipboard Screws

Chipboard screws vary depending on their head type, coating, and length.

4.1. By Head Type

• Countersunk Head Screws:
  Sit flush with the surface for a clean look.

• Star Countersunk Screws (PH or PZ):
  Prevent slippage during tightening and allow higher torque.

• Truss Head Screws:
  Sit on the surface without embedding, providing a larger holding area.

4.2. By Coating

• Yellow Zinc-Plated Screws: Corrosion-resistant and commonly used in furniture.

• White Galvanized Screws: Stronger rust resistance, ideal for humid environments.

• Black Phosphate Screws: Preferred for specific applications requiring a dark finish.

4.3. By Length

• Short Screws (13 mm – 30 mm): For thin panels and accessories like hinges.

• Medium Screws (35 mm – 50 mm): The most widely used sizes for general furniture assembly.

• Long Screws (55 mm – 120 mm): For thicker panels, frames, or heavy-duty connections.

5. Tips for Using Chipboard Screws

• Correct Length Selection: Screw length should be at least two-thirds of the material’s thickness.

• Proper Bit Choice: PH2 or PZ2 bits are the most common.

• Pre-Drilling: Recommended for hard MDF or thick panels to prevent splitting.

• Torque Adjustment: Avoid overtightening with power tools to prevent head stripping.

• Coating Selection: Use galvanized or yellow zinc screws in humid environments.

6. Advantages of Chipboard Screws

• Easy installation with high holding power

• Cost-effective and long-lasting fastening solution

• Available in various sizes, head types, and coatings for different applications

• Countersunk head designs ensure a smooth, flush finish

⭐ Conclusion

Chipboard screws offer strong, economical, and practical solutions for all furniture and wood-based applications.
