Notification
 Hexagon Head Screws (IS 1363 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. This Order supersedes the earlier QCO of 2023, establishing mandatory BIS certification for screws in the specified category.
Enforcement Timeline
- Large and Medium Enterprises: 1 August 2024
- Small Enterprises: 1 November 2024
- Micro Enterprises: 1 February 2025
Overview
Hexagon head screws are threaded fastening devices with a hexagonal head, widely used in engineering, automotive, structural, and machinery applications. Unlike bolts, screws are often designed for direct assembly without a nut, making dimensional accuracy and strength critical. IS 1363 (Part 2):2018 provides specifications ensuring that screws conform to required standards for safety, interchangeability, and performance.
Objective & Scope
The purpose of IS 1363 (Part 2):2018 is to regulate the quality and dimensions of hexagon head screws used in industrial and structural applications. The scope covers manufacturing tolerances, material selection, mechanical strength, corrosion resistance, and testing methods. It ensures that screws provide reliable fastening, resist loosening under load, and remain compatible with standardized nuts and washers.
Products Covered
This standard applies to Hexagon Head Screws with sizes ranging from M5 to M64. These screws are generally manufactured from carbon steel or alloy steel and are suitable for applications in general engineering, structural assemblies, automotive components, and machinery.
Exemptions Provided
 As per the 2024 QCO, the following exemptions are applicable:
- Goods manufactured domestically for export purposes.
- Imports as part of a finished product, sub-assembly, or component.
- Products manufactured by micro-enterprises registered on the Udyam Portal, with plant & machinery investment ≤ ₹25 lakhs and turnover ≤ ₹2 crores.
- Temporary exemptions (up to 3 years) for manufacturers importing fasteners for use in export-oriented production.
- Import of up to 200 kg annually for research & development purposes.
- Up to 5% of the 2023–24 import value of nuts, bolts, and fasteners allowed for spares or after-sales service.
Industries Impacted
Fastener and Screw Manufacturers – directly responsible for BIS compliance.
Automotive & Aerospace Sectors – rely heavily on certified screws for safety-critical joints.
Construction & Infrastructure – need standardized screws for load-bearing assemblies.
Machinery & Equipment Manufacturers – must source BIS-marked screws for compliance.
Importers & Exporters – subject to certification requirements and conditional exemptions.
Mandatory Compliance Requirements
All Hexagon Head Screws (IS 1363 Part 2:2018) must bear the ISI mark.
Certification is compulsory under Scheme-I of BIS (Conformity Assessment) Regulations, 2018.
