BIS CERTIFICATION OF CROSS RECESSED DRILLING SCREWS WITH TAPPING SCREW THREAD PART 3 RAISED COUNTERSUNK HEADAS PER IS 18471 (PART 3): COMPREHENSIVE GUIDE BY OMEGA QMS PVT. LTD.

INTRODUCTION

In today’s fast-paced industrial landscape, the importance of standardized components cannot be overstated.

Fasteners are critical components in construction, manufacturing, and mechanical applications. Among these, cross recessed drilling screws with tapping screw threads are uniquely designed for efficient drilling and fastening. The Indian Standard IS 18471 (Part 3) specifically addresses the characteristics of raised countersunk head drilling screws, which are integral in various industries, ensuring strong and secure connections without the need for pre-drilled holes. This article delves into the specifics of this standard, the Bureau of Indian Standards (BIS) certification scheme, and the role of Omega QMS Pvt Ltd in facilitating BIS certification for manufacturers.

SUMMARY OF INDIAN STANDARD IS 18471 (PART 3)

IS 18471 (Part 3) is the Indian adaptation of ISO 15483:1999, which specifies the requirements for cross recessed raised countersunk head drilling screws with tapping screw threads. The standard covers various sizes, from ST2.9 to ST6.3, and is part of a broader series on fasteners, with other parts addressing pan head and countersunk head screws.

Dimensions :  It details the dimensions, including head diameter, recess type, and drilling point specifications. The screws are typically made from steel and may have various finishes, including plain and electroplated coatings.

Designations: The standard provides a method for designating these screws, incorporating thread size, length, and recess type.

Mechanical Properties : The screws must meet specific mechanical properties, such as hardness and tensile strength, ensuring they perform effectively under different conditions.

Tolerances : Tolerances for dimensions and mechanical properties are specified to ensure the screws meet precise manufacturing standards, as detailed in ISO 4759-1.

QUALITY CONTROL ORDER (TECHNICAL REGULATION) ISSUED BY THE DEPARTMENT FOR PROMOTION OF INDUSTRY AND INTERNAL TRADE, MINISTRY OF COMMERCE AND INDUSTRY, GOVT. OF INDIA FOR MANDATORY BIS CERTIFICATION

The DPIIT, Ministry of Commerce & Industry, Govt. of India, has issued a Quality Control Order making it mandatory for all cross recessed screws to be used in India, whether manufactured in India or imported from foreign countries, shall mandatorily carry the Standard Mark of the Bureau of Indian Standards under a valid BIS licence.

BIS CERTIFICATION SCHEME FOR IS 18471 (PART 3): 2023

The BIS certification mark not only confirms compliance with Indian standards but also enhances the credibility and marketability of cross-recessed screws. Specifically, under IS 18471 (Part 3): 2023, the screws must pass stringent tests to verify their suitability for use in high-performance applications across industries such as construction, automotive, and machinery.

Key areas of evaluation in the certification process include:

Material Composition: The screws are tested for their chemical composition to ensure that they are made from high-quality materials, such as carbon steel or stainless steel, which provide necessary mechanical strength and corrosion resistance. 

Dimensional Accuracy: A critical requirement of IS 18471 (Part 3) is ensuring the precise dimensions of the screws, particularly in the cross-recess design, which allows for optimal torque application. Any deviation from the specified tolerances can affect the screw’s functionality and ease of installation.

Mechanical Performance: The screws undergo performance testing to measure tensile and shear strength. This ensures that they can withstand operational loads without failing or deforming. Proper torque capacity also ensures secure fastening in applications where vibrations or dynamic loads are present.

Surface Coating: In industries where screws are exposed to harsh environmental conditions, the BIS certification also confirms that the surface finish, such as zinc coating or phosphating, meets corrosion resistance requirements. This protects the screws from rusting, prolonging their lifespan and reliability in the field.

Additionally, BIS certification ensures that the manufacturing process is consistent and adheres to quality control practices. This ensures that each batch of screws produced meets the same quality standards, maintaining uniformity in performance.

For manufacturers, having the BIS mark on their cross-recessed screws serves as a testament to the product’s quality and compliance with safety and performance standards. It not only helps them gain consumer trust but also simplifies regulatory approval processes for export to global markets, where recognized standards like BIS serve as a benchmark of quality.

In summary, BIS certification under IS 18471 (Part 3): 2023 for cross-recessed screws is an essential validation of product quality, offering benefits in terms of market competitiveness, consumer confidence, and compliance with international norms. The certification ensures that these screws perform reliably in demanding environments, making them a trusted choice for critical applications.
