BIS Certification for Chipboard Screws – Complete Guide to IS 18508:2024
BIS certification for Chipboard Screws confirms that these fasteners comply with IS 18508:2024, ensuring proper thread design, tensile strength, and corrosion resistance. It is required in India to guarantee reliable fastening in particle boards and engineered wood, preventing structural failure and ensuring consistent product quality across manufacturing batches.
Chipboard screws are specifically designed fasteners used for joining particle boards, MDF (medium-density fiberboard), plywood, and other engineered wood materials. These screws are widely used in furniture manufacturing, modular kitchens, cabinetry, interior fit-outs, and construction frameworks.
Unlike traditional wood screws, chipboard screws are engineered with deeper threads and sharper points to provide enhanced grip in softer and compressed wood materials. They are essential in applications where holding strength, precision, and long-term stability are critical.
India's booming furniture and real estate sectors have significantly increased the demand for chipboard screws. From ready-to-assemble furniture to large-scale interior installations, these fasteners are used in massive volumes. However, their performance directly impacts the safety and durability of the final product.
If chipboard screws are poorly manufactured—such as having weak threads, improper hardness, or inconsistent dimensions—they may strip, break, or loosen over time. This can lead to unstable furniture, structural failures, and costly repairs.
To ensure reliability, India has established IS 18508:2024, a standard that defines requirements for chipboard screws in terms of design, material properties, and performance.
Obtaining a BIS Certification for Chipboard Screws ensures that the product meets these requirements. For manufacturers and importers, securing a BIS License for Chipboard Screws is crucial to ensure compliance and maintain credibility in the Indian market.

Understanding BIS Certification for Chipboard Screws
Chipboard screws are designed for specific applications where conventional fasteners may not perform effectively. Their unique thread geometry allows them to grip engineered wood materials without causing splitting or damage.
The BIS Certification for Chipboard Screws evaluates whether these screws meet the functional and structural requirements necessary for such applications.
For example, when assembling modular furniture, chipboard screws must:
- Penetrate particle board smoothly without cracking it
- Maintain strong holding power under load
- Resist loosening over time due to vibration or usage
- Provide consistent performance across different board densities
Certification ensures that these characteristics are achieved through proper design and manufacturing.
Testing focuses on:
- Thread depth and pitch for optimal grip
- Material strength to withstand torque during installation
- Resistance to wear and deformation
- Surface coatings to prevent corrosion
A BIS Certificate for Chipboard Screws confirms that these parameters have been verified.
Consistency is another critical factor. Furniture manufacturers rely on uniform quality across thousands of screws. Certification ensures that each batch meets the same standards, reducing the risk of product failure.

FAQs – BIS Certification for Chipboard Screws - IS 18508:2024
1. What makes chipboard screws different under IS 18508:2024 compared to normal wood screws?
IS 18508:2024 specifically focuses on screws designed for engineered wood like particle board and MDF. Unlike traditional wood screws, chipboard screws have deeper threads and sharper points. The standard ensures optimized thread geometry, better holding strength, and reduced splitting of boards, making them suitable for modern furniture manufacturing applications.
2. How does IS 18508:2024 ensure proper thread performance in chipboard screws?
The standard defines strict parameters for thread pitch, depth, and angle to ensure strong engagement with compressed wood materials. Testing verifies that screws provide consistent grip without damaging the board. This is crucial because chipboard materials are less dense and require specially designed threads for effective fastening.
3. Why is tensile strength important in BIS Certification for Chipboard Screws?
Tensile strength determines how much load a screw can withstand before breaking. Under IS 18508:2024, screws are tested to ensure they do not snap during installation or under load. This is essential for furniture joints, where weak screws can lead to structural instability and product failure over time.
4. How does IS 18508:2024 address torque resistance in chipboard screws?
Torque resistance testing ensures that screws can handle the force applied during tightening without stripping the head or threads. The standard evaluates whether the screw head maintains its shape and functionality when driven into dense boards, ensuring smooth installation and long-term reliability.
5. Are corrosion resistance requirements included in IS 18508:2024?
Yes, the standard includes requirements for surface coatings such as zinc plating or other finishes. These coatings are tested for durability and resistance to rust, especially in humid environments. This ensures that screws maintain strength and appearance even when used in kitchens, bathrooms, or outdoor furniture.
6. Can chipboard screws of different head types be certified under IS 18508:2024?
Yes, the standard covers various head designs, provided they meet dimensional and performance requirements. Whether it is countersunk or other compatible head types, each design must ensure proper seating, torque transfer, and compatibility with tools, while maintaining the structural integrity of the fastening.
7. How does BIS Certification ensure dimensional accuracy of chipboard screws?
IS 18508:2024 specifies exact tolerances for length, diameter, thread spacing, and head dimensions. Laboratory testing checks these parameters using precision instruments. Accurate dimensions ensure compatibility with tools and materials, preventing issues like improper fitting or weak fastening in furniture assemblies.
8. What happens if chipboard screws fail IS 18508:2024 testing?
If screws fail testing—due to poor strength, incorrect dimensions, or coating issues—the manufacturer must improve design or material quality. The product must then be retested. Certification is only granted when all parameters meet the standard, ensuring only reliable products reach the market.
9. Does IS 18508:2024 consider performance in different board densities?
Yes, chipboard screws are designed for varying densities of engineered wood. The standard ensures that screws perform consistently across different materials such as MDF and particle board. Testing verifies that the screw maintains grip without causing splitting or loosening in different substrates.
10. How does BIS Certification help furniture manufacturers using chipboard screws?
Certified screws provide consistent quality, reducing production defects and assembly failures. Manufacturers can rely on uniform performance across batches, ensuring stable joints and durable furniture. This minimizes warranty issues and enhances customer satisfaction, especially in modular and ready-to-assemble furniture systems.
