Specialized fasteners known as high-strength structural nuts are essential for attaching heavy-duty structural connections and components in a variety of sectors, such as engineering, manufacturing, and construction. In crucial applications, these nuts are made to support heavy weights and offer a reliable, long-lasting connection. The outstanding load-bearing ability of high-strength structural nuts is one of its main characteristics. Structural assemblies are guaranteed stability and safety since they are designed to withstand severe pressures and stresses without deforming or losing their integrity. These nuts are frequently used to create a strong and trustworthy fastening system with high-strength bolts or threaded rods.
High-strength structural nuts are produced in accordance with specified quality requirements thanks to IS 6623:2004. Respecting this guideline aids producers in creating nuts that satisfy safety regulations, guaranteeing the dependability and stability of constructions. The requirements for large-scale, high-strength structural steel nuts that is, hexagonal nuts that fall within property classes 8 and 10 are described in this standard. These nuts come in sizes ranging from M 12 to M 36 and are intended for use in structural steel connections, whether they entail friction-type or bearing-type connections.
Note: It is obligatory for producers of structural nuts with high strength to get the ISI Mark Certification before to introducing their products into the Indian market.
High-strength structural nuts must be ISI certified in order to comply with the technical requirements and safety guidelines established by the BIS. This certification ultimately ensures the dependability and safety of infrastructure projects and structures. Given that high-strength structural nuts are essential to the stability and safety of infrastructure and buildings, this certification for these nuts guarantees that they meet established technical standards and helps to reinforce the confidence that construction professionals have in the products they use.
Indian Standards Institute, or ISI was renamed the Bureau of Indian Standards (BIS) in 1987. The official mark that the Bureau of Indian Standards provides for manufacturers of various goods is the ISI Mark. It is used to indicate compliance with Indian standards (IS) set by the Bureau of Indian Standards (BIS) and has been used as a conformity marking for industrial products. Manufacturers received permission from BIS to use the ISI Mark on items that comply with relevant Indian requirements through the product certification program.
Only manufacturers (domestic or foreign) who produce the finished product will be awarded ISI Certification. This will not be given to any product importers, traders, dealers, or distributors.
The following documentation is required to get an ISI certification:

There are two approaches for Indian manufacturers to become certified with the ISI Mark:
Regular Procedure
With the possible exception of cases deemed "All India first," which might take up to 180 days, the licensing procedure is expected to be finished in 120 days. This timeline starts on the day the application is received, assuming that at different points in time the documentation, unit assessment, and product conformance are all deemed acceptable.
Step 1: Manufacturing Unit Customization in Compliance with Applicable Indian Standards
Step 2: Submission of the Application Form

Simplified Procedure
This is a much faster process than the standard procedure. After a factory inspection is deemed satisfactory and the initial evaluation establishes that the sample complies with the applicable Indian Standard(s), the license application process is expected to be finished in 30 days.
Step 1: Adapting the Manufacturing Unit to Comply with the Relevant Indian Standard
Step 2: Sample Testing
