bis-isi-mark-registration-for-raised-countersunk-head-screws-type-h-type-z-is-7486-2018-iso-7047-2011The framework of industrial fasteners in India has fundamentally shifted. Manufacturers, importers, and vendors dealing with Raised Countersunk Head Screws (Common Head Style) must immediately recognize a critical new mandate. These specific screws—characterized by the distinct Type H or Type Z cross recesses—are now subject to mandatory certification by the Bureau of Indian Standards (BIS).

This is not a suggestion for best practice; it is a legal requirement. Failure to comply with the necessary technical specifications and obtain the ISI Mark will result in direct market prohibition. The government’s intent here is clear: to ensure every fastener used in the nation meets a non-negotiable threshold of quality and reliability

New Quality Mandate

This sweeping regulatory change is formalized through the Cross Recessed Screws (Quality Control) Extension Order 2025. The order has been instituted by the Ministry of Commerce and Industry operating through the Department for Promotion of Industry and Internal Trade (DPIIT)

Simply put, the Order makes adherence to the stipulated Indian Standard and the affixing of the ISI Mark compulsory for market access. The entire process of checking conformity and granting licenses falls under the strict purview of the BIS.

The legal gravity of this situation cannot be overstated. Any entity that manufactures, sells, or imports these screws without a valid BIS license will face punitive actions. These penalties are severe and are laid out explicitly within the framework of the BIS Act, 2016. For any business, compliance is now the singular route to continued viability in the Indian fastener market.

Technical Definition

The relevant technical guideline for this compulsory marking is IS 7486: 2018. This Indian Standard is fully synchronized with the international specification ISO 7047: 2011, ensuring that the nationally mandated quality aligns with global best practices

The standard particularly attacks screws characterised in terms of geometry and drive type. One of its distinguishing features is the Raised Countersunk Head. The style is a small dome shape that is slightly higher than the fastened surface, and in contrast to a flat countersunk head, it has a finished appearance without leaving the screw protruding under the dome. The recess types covered by this mandate are critical to driver engagement:

  • Type H Recess: The standard cross-recess often referred to as Phillips
  • Type Z Recess: The advanced cross-recess typically identified as Pozidriv offering superior cam-out resistance

Furthermore the standard demands Product Grade A which signifies extremely tight tolerances and high precision in manufacturing. Compliance means mastering all dimensional, material and mechanical specifications detailed within this rigorous framework.

The Phased Implementation Timeline

In its bid to have a seamless transition instead of the chaos that may ensue, the government has put a practical, gradual process of QCO implementation in place. This arrangement will enable the small manufacturers to have breathing space to adjust their production lines and pass the certification process.

Manufacturers must clearly identify their enterprise category to determine their absolute compliance deadline. The timelines are categorized based on the classification criteria of the Ministry of MSME:

  • General Implementation Deadline (Medium and Large Enterprises): All non-exempt screws must be certified by November 1, 2025.
  • Small Enterprises: Have an extended period until February 1, 2026.
  • Micro Enterprises: Are granted the longest grace period, with their deadline set for May 1, 2026.

These dates represent the point of no return. Businesses that delay application and quality system integration until the last moment risk severe supply chain interruptions and being forced out of the market entirely.

The Non-Negotiable Path to Certification

Regardless of whether it is domestic manufacturers or foreign manufacturers (under the Foreign Manufacturers Certification Scheme or FMCS) the basic steps are the same:

  1. Comprehensive Application: Submission of detailed application forms and all required documentation establishing the factory’s legal and operational standing
  2. Factory Inspection and Audit: A mandatory visit by BIS auditors to the manufacturing premises. Their goal is to verify that the entire production and quality infrastructure fully aligns with BIS protocols
  3. Independent Product Testing: Samples of the screw product must be drawn by the BIS team and subjected to exhaustive testing at recognized external laboratories, proving conformity to every technical clause of IS 7486: 2018
  4. License Grant: Only after the facility audit and all sample testing are satisfactory will the BIS issue the license. The ISI Mark can then be legally applied establishing the product’s validated quality

Conclusion

The application of ISI Mark to Raised Countersunk Head Screws in the IS 7486: 2018 is a big step towards the Indian fastener industry. This regulation is a control of quality that all the products reach a level of reliability.

For every manufacturer and importer this is a clear call to action. Proactive engagement with the BIS process is now a fundamental part of a sound business strategy. Only certified products will be deemed legal after the respective deadlines making rapid compliance the only way to secure continued and legitimate operation in the competitive Indian marketplace
