BIS Certification for Machine Screws / Standard Fasteners
13. April 2026Machine screws and standardized fasteners (standard fasteners) are subject to mandatory BIS certification in India where applicable under regulatory requirements. These classic metric screws are widely used in mechanical, industrial, and assembly applications and must comply with defined specifications regarding dimensional accuracy, mechanical strength, and material quality.
Compliance with Indian Standards (IS), which are partly aligned with ISO specifications, ensures product reliability and performance. BIS certification is required for market access in India and is typically granted under the ISI Certification Scheme. The process includes product testing and factory inspection.
BIS Certification under IS 7483
IS 7483 specifies requirements for certain types of metric machine screws used in general engineering and industrial applications.
The standard covers:
- Dimensions and thread specifications
- Mechanical strength properties
- Material requirements
- Tolerances and surface characteristics
BIS certification requires:
- Testing in BIS-recognized laboratories
- Verification of mechanical performance
- Factory inspection to ensure consistent production quality
BIS Certification under IS 7485 (Part 1 & 2)
IS 7485 (Part 1 and Part 2) is based on ISO-adopted specifications for standardized screws and defines technical requirements for various screw types and applications.
It includes:
- Geometrical and thread parameters
- Strength classes and mechanical properties
- Material specifications and heat treatment
- Manufacturing and quality requirements
Under the BIS ISI Scheme, certification involves:
- Comprehensive product testing
- Evaluation of manufacturing processes
- Audit of in-house quality control systems
BIS Certification under IS 7486
IS 7486 defines additional requirements for metric machine screws and standardized fasteners used in industrial applications.
The standard regulates:
- Dimensional and thread specifications
- Mechanical performance characteristics
- Testing methods for compliance verification
- Material and processing requirements
Certification includes:
- Laboratory testing according to IS requirements
- Factory inspection by BIS authorities
- Ongoing surveillance after certification
Is BIS Certification Mandatory for Machine Screws?
Yes. If machine screws fall under mandatory BIS regulation, certification is required prior to import, distribution, or sale in India. Products without valid BIS certification are not permitted for market access.
What Is the BIS Certification Procedure?
The certification process typically includes:
- Identification of applicable Indian Standards (e.g. IS 7483, IS 7485, IS 7486)
- Product testing in BIS-approved laboratories
- Preparation and submission of technical documentation
- Factory inspection conducted by BIS
- Grant of ISI license upon successful evaluation
Both domestic and foreign manufacturers must comply with these requirements.
How Long Does BIS Certification Take?
The timeline depends on product scope, testing requirements, and factory readiness. In most cases, the process takes several weeks to a few months.
