BIS Certification for Drywall Screws IS 18507

BIS Certification is mandatory under IS 18507 for Drywall Screws. It ensures the quality and performance measures, which are important for industry standards, especially for drywall installation, interior construction, and partition systems.

Drywall screws have reliable holding power, performance, durability, and ability to penetrate underneath surface. By obtaining IS 18507, manufacturers ensure that the product upholds a high expectation of material quality, thread quality, and mechanical performance. This allows the industry to rly on drywall screws to provide stable long-lasting installation for any job. Let’s know more about the Certification of Drywall Screws – Specification.

Drywall Screws Product Certification Overview

Drywall screws are an important type of fastener, used to join sheets of drywall to wood and metal studs. They have a sharp point to penetrate a variety of drywall types and use either coarse or fine thread patterns. It provides a dependable grip, depending on the type of material they are fastening. The 'countersunk head' form of drywall screws allows them to lie flush with the drywall surface. They are also coated in a phosphate finish to help create a corrosion-resistant bond. They can be used in a residential or commercial construction project.

BIS certification means that drywall screws meet the requirements of Indian quality standards and safety. When a manufacturer intends to distribute drywall screws in the Indian market they are obliged to comply with the technical requirements and safety standards contained in IS 18507. This certification means that the screws meet agreed to performance criteria meaning they will perform the job adequately and have an acceptable degree of reliability, strength and durability when used in construction.

Quality Control Order for Drywall Screws

The BIS Certification is mandatory for drywall screws under Cross Recessed Screws (Quality Control) Order, 2024, issued by Ministry of Commerce and Industry, specifically the Department for Promotion of Industry and Internal Trade (DPIIT).

According to this rule, before a product may be sold in India, its maker must receive BIS certification to utilise the ISI Mark (Standard Mark).  The certification ensures that the screws meet national quality standards, promoting consumer safety and confidence. The 2016 Bureau of Indian Standards Act imposes penalties for noncompliance with this rule.

Whether you are a manufacturer looking to enhance product credibility or a buyer in search of reliable fastening solutions, BIS certification for drywall screws guarantees adherence to high industry standards. In this guide, we will explore the significance of IS 18507, the certification process, and how it impacts the construction landscape.

Scope of Drywall Screws – Specification for BIS Certification

The Indian Standard for drywall screws is covered under IS 18507.  It includes the requirements for a trumpet or bugle head that is cross-recessed and has a thread diameter between 3.5 and 5.5 mm. This outlines the requirements for materials, thread design, head styles, and mechanical properties to ensure consistent performance and reliability in various construction and interior design applications.

Drywall screws are used to attach drywall sheets o either wooden or metal studs. They feature a sharp point that allows for easy penetration into the drywall. Additionally, drywall screws have a countersunk head, which enables them to sit flush with the surface of the drywall. They are coated with phosphate to resist corrosion, making them effective for residential and commercial construction projects.

Key Highlights of IS 18507

The IS 18507 is an Indian Stanard which sets the specification for drywall screws, as it ensures the quality and safety of product. It outlines the manufacturing, testing, and performance requirements. It also includes material composition, thread design, and mechanical properties. Let’s go through the important highlights of IS 18507:

• Thread Size: The standard applies to screws with thread sizes between 3.5 mm - 5.5 mm. 
• Design and Head Types: The screws are made as either cross-recessed bugle-head or cross-recessed trumpet head screws. 
• Material and Finish: The screws may be manufactured from steel, stainless steel or non-ferrous materials, then the screws will be finished with either a phosphate or electroplated finish.
• Hardness and Torque Requirements: The screws must have a surface hardness of 550 HV 0.3 - 800 HV 0.3. The different sizes of screws have specific braking torque requirements.
• Scope: The standard applies to cross-recessed drywall screws such as bugle and trumpet head screws that have thread sizes between 3.5 mm - 5.5 mm Switzerland.
• Material Requirements: The standard outlines what material is to be used in making up the drywall screws and ensures they meet the standard for steel products of the Bureau of Indian Standards (BIS) regarding strength and corrosion resistance.
• Mechanical property requirements: The standard outlines the mechanical property requirements of the screw in terms of pull-out strength and twisting resistant that ensures that they are capable of use under their intended-stresses, while remaining flexible to accommodate the stresses of use.
• Testing: The standard outlines the rigid pull-out strength testing, corrosion testing, and tolerance testing to ensure reliability and suitability in a range of conditions.

BIS Certification Process for Drywall Screws – Specification IS 18507

The following steps describe the process of obtaining BIS Certification:

• Confirm Applicability: If the product is an IS 18507, you would need to apply for a BIS licence using IS 18507.
• Online Application: The BIS licence application will need to be submitted through the online portal.
• Inspection and Testing by BIS: BIS inspectors will visit your Production Facility to evaluate: Production procedures and equipment devices are assessed in terms of your quality assurance measures.
• Test Samples: BIS will take product samples to a BIS-accredited testing facility. The sample sent to test for IS 18507 will be the sample for tensile strength, elongation, and chemical resistance.
• Compliance: The BIS will examine the inspection and testing reports to determine compliance with the standard.

You could undertake the BIS process to certify your product for Indian and foreign manufacturers:

• BIS Mark Certification Process for Indian Manufacturers
• BIS Mark Certification Process for Foreign Manufacturers
