Notification
Hexagon Head Bolts, Screws, and Nuts of Product Grade C (IS 1363 Part 1:2019) 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.
Enforcement Timeline
- Large and Medium Enterprises: 1 August 2024
- Small Enterprises: 1 November 2024
- Micro Enterprises: 1 February 2025
Overview
Hexagon head bolts are essential fasteners widely used in construction, engineering, automotive, heavy machinery, and infrastructure sectors. They ensure reliable mechanical joints by providing tensile strength, shear resistance, and dimensional stability. IS 1363 (Part 1):2019 prescribes technical specifications for Grade C bolts, emphasizing uniformity, material quality, mechanical strength, and thread dimensions. Their standardization is crucial to ensure safety, interchangeability, and compatibility across industries.
Objective & Scope
The purpose of IS 1363 (Part 1):2019 is to regulate the quality and dimensional accuracy of Grade C hexagon head bolts to ensure they meet performance and safety requirements. The scope covers specifications for materials, manufacturing tolerances, mechanical properties, corrosion resistance, and testing methods. The standard ensures reliability in fastening applications and minimizes risks of mechanical failure.
Products Covered
This standard applies to Hexagon Head Bolts of Product Grade C, with a size range from M5 to M64. These bolts are typically manufactured from carbon steel or alloy steel and are intended for general engineering, machinery, structural assemblies, and industrial applications.
