Notification
Hexagon Head Screws of Product Grades A and B (IS 1364 Part 2:2018) have been notified under the Bolts, Nuts and Fasteners (Quality Control) Order, 2024, issued via S.O. 2771(E) dated 12 July 2024 by the Ministry of Commerce & Industry under the BIS Act, 2016. The 2024 Order superseded the earlier QCO of 2023, making BIS certification mandatory for these precision-grade screws.
Enforcement Timeline
- Large and Medium Enterprises: 1 August 2024
- Small Enterprises: 1 November 2024
- Micro Enterprises: 1 February 2025
Overview
Hexagon head screws are widely used threaded fasteners with a hexagonal head, designed to be tightened using a spanner or wrench. Unlike bolts, screws are frequently used for direct assembly into tapped holes, making dimensional precision and strength critical. IS 1364 (Part 2):2018 covers Grades A and B hexagon head screws, which are higher precision fasteners compared to Grade C, and are vital in automotive, machinery, aerospace, and structural applications where reliability and accuracy are essential.
Objective & Scope
The objective of IS 1364 (Part 2):2018 is to ensure quality, precision, and uniformity in the production of hexagon head screws of Grades A and B. The scope includes specifications for dimensions, tolerances, material quality, mechanical strength, surface finish, corrosion resistance, and testing protocols. The standard provides assurance of compatibility with standardized nuts and washers, minimizing risks of loosening or joint failure under load.
Products Covered
This standard applies to Hexagon Head Screws of Product Grades A and B, with a size range from M1.6 to M64. These screws are typically manufactured from carbon steel or alloy steel and are used in precision engineering, high-strength structures, automotive systems, heavy machinery, and aerospace assemblies.
Exemptions Provided
As per the 2024 QCO, the following exemptions are applicable:
- Screws manufactured domestically exclusively for export.
- Screws imported as part of a finished good, sub-assembly, or component.
- Screws manufactured by micro-enterprises registered on the Udyam Portal, where plant & machinery investment ≤ ₹25 lakhs and turnover ≤ ₹2 crores.
- A 3-year exemption for manufacturers importing screws solely for use in export-oriented manufacturing.
- Import of up to 200 kg annually for research and development purposes.
- Up to 5% of the 2023–24 import value permitted for spares or after-sales service.
Industries Impacted
- Fastener Manufacturers – responsible for BIS certification and compliance.
- Automotive & Aerospace Sectors – critical users of high-precision screws.
- Construction & Structural Engineering – require certified screws for safety-critical joints.
- Machinery & Heavy Engineering – must procure BIS-marked screws to maintain reliability.
- Importers & Exporters – subject to certification mandates with limited exemptions.
Mandatory Compliance Requirements
- All Hexagon Head Screws under IS 1364 (Part 2):2018 must bear the ISI mark.
- Certification is mandatory under Scheme-I of BIS (Conformity Assessment) Regulations, 2018.
- Testing and evaluation must be done through BIS-recognized laboratories.
- Packaging and labeling must prominently display the ISI mark before marketing or distribution.
Next Steps for Stakeholders
- Manufacturers: File applications for BIS certification, upgrade testing processes, and ensure compliant labeling.
- Importers: Review exemption criteria, maintain proper audit documentation, and declare old stock as required.
- OEMs & Assemblers: Revise sourcing practices to procure only BIS-certified screws.
- Industry Associations: Facilitate knowledge-sharing and compliance support for MSMEs.
Legal Provisions, Enforcement & Penalties
Enforcement is governed under the BIS Act, 2016, with BIS as the certification and enforcement authority. Non-compliance may result in seizure of products, fines, suspension of licenses, and imprisonment up to two years, or both.
Conclusion
From 1 August 2024 (with staggered timelines for SMEs), Hexagon Head Screws of Grades A and B (IS 1364 Part 2:2018, Size M1.6–M64) must carry BIS certification and the ISI mark. The 2024 QCO replaces the 2023 Order, strengthening India’s regulatory framework for precision fasteners. Early compliance is essential for manufacturers and importers to ensure uninterrupted production, trade, and supply across industries.
