The Hexagon Head Screws form a part of the widely used class of screws in engineering, construction, automotive, machinery, infrastructure and industries. Such screws are intended to offer fastening and mechanical performance as per the conditions under which they would be employed. As such fasteners are very important for providing structural stability and security of the assembly; it becomes essential that the products meet the requirements laid down by IS 1364 (Part 2):2023 / ISO 4017:2022.
As per Indian Standards, the hexagon head screws need to comply with technical specifications relating to their dimension, thread, mechanical performance, material quality, tensile strength, surface finish, and other such performance-related requirements. The conformity to QCOs of the Bureau of Indian Standards (BIS) and Indian Standards is mandatory where applicable. The ISI Mark on hexagon head screws indicates conformity to prescribed quality standards.
The Indian Standard IS 1364 (Part 2):2023 is equivalent to the international standard ISO 4017:2022 and lays down the requirements of hexagon head screws of product grades A and B of the sizes M1.6 to M64. Requirements related to dimensions, tolerances, thread form, and properties have been detailed. According to the BIS requirement, hexagon head screws are -
BIS certification under IS 1364 (Part 2):2023 is required for organizations involved in the manufacturing, import, or supply of hexagon head screws covered under the applicable Quality Control Orders.

Hexagon Head Screw BIS Certification Under IS 1364 (Part 2):2023 is important in adhering to Indian quality standards concerning dimensions, mechanical properties, and reliability. This is a way of confirming that the product is up to the required standards and fit for industrial use.
In order to ensure that there is high quality, durability and mechanical properties of hexagon head screws, the Bureau of Indian Standards provides certain specifications for inspection and tests as per IS 1364 (Part 2):2023 / ISO 4017:2022. The certificate thus issued proves that the manufacturers always manufacture screws which meet all the required dimensional, material, thread, and mechanical property specifications. They also prove that they are capable of withstanding operational loads.
The BIS testing parameters for Hexagon Head Screws (Size Range M1.6 to M64) are as follows:
Procedure for BIS ISI Certification under IS 1364 (Part 2):2023
The BIS Certification for hexagon head screw ensures that the hexagon head screw meets the Indian Standard requirements laid down. The BIS certification is done under Scheme I of BIS and goes through various steps.
Foreign manufacturers need to appoint an Authorized Indian Representative (AIR) in India. This person is the local point of contact for the Bureau of Indian Standards (BIS) and takes care of all rules and compliance work in India.
After a manufacturer receives BIS approval, the ISI mark for Hexagon head screws (size range M1.6 to M64) as per IS 1364 (Part 2):2023/ISO 4017:2022 is mandatory to be permanently stamped on the product or packing or both. ISI Mark together with other important parameters like identification of the manufacturer and certification marks licence number (CM/L) are essential. It is to be ensured that the product fulfills all dimensions, mechanical, and other important aspects as per the relevant Indian Standard. Further information can be found below:
Note: Marking is typically applied using durable stamping, tagging, or permanent printing to ensure clear identification during handling, storage, and transportation, as per BIS marking requirements.
The charges for BIS Certification of Hexagon Head Screws (Size Range M1.6 to M64) as per IS 1364 (Part 2):2023 include Application Charges, Factory Inspection Charges, Licence Issue Charges, Testing Charges and Marking Charges as applicable.
Note -
The manufacturers could face some problems when applying for BIS certification of hexagon head bolts according to IS 1364 (Part 2):2023.
Hexagonal head screws are important screwing elements that are extensively used in various industries and engineering applications. Performance of these fasteners has direct impact on the safety and durability of the assembled constructions. Adherence to IS 1364 (Part 2):2023/ISO 4017:2022 ensures that the fasteners are of high quality with respect to dimensions, strength, thread accuracy and uniform production. Certification by BIS shows conformity to Indian quality standards and enables manufacturers to mark their products with ISI. This helps in increasing the credibility and acceptance of the product in the market besides improving customer satisfaction. Manufacturers who wish to get their products certified may seek help from qualified and experienced BIS consultants like EVTL India.
