BIS Certification for Hexagon Head Screw IS 1363 (Part 2) :2018

Hexagon head screws are commonly used fasteners in construction, machinery, and general engineering work where secure tightening and easy installation are required. These screws are designed to provide strong holding and are widely used in assemblies where bolts may not be suitable, making them important for everyday industrial and mechanical applications.

To ensure their quality and proper performance, the Bureau of Indian Standards provides BIS certification as per the Indian Standard IS 1363 (Part 2): 2018. This certification ensures that the screws meet required standards in terms of size, threading, material quality, and strength. What is IS 1363 (Part 2): 2018

what is is 1363 (part 2): 2018

IS 1363 (Part 2): 2018 is the Indian Standard for hexagon head screws. This standard is set by the Bureau of Indian Standards to make sure these hex screws are safe to use, properly manufactured, and consistent in quality.

This standard ensures that the screws are:

Properly sized with accurate threads for tight and secure fitting

Material Tests

Raw Material Quality (S) – Confirms material meets required standards
Property Class Verification (R) – Ensures screws meet declared strength class
Heat Treatment Check (R) – Ensures proper hardness and strength after processing

Performance and Strength Tests

Tensile Test (R) – Checks strength under pulling force
Proof Load Test (R) – Ensures screws can handle working load
Torsion Test (R) – Checks resistance to twisting forces
Impact Test (R) – Ensures durability under sudden loads
Hardness Test (R) – Checks resistance to wear and deformation

Surface and Finish Tests

Coating/Finish Check (R) – Verifies surface condition like electroplating or coating
Surface Discontinuity Inspection (R)—Ensures no cracks or defects on surface
Coating Quality Test (R) – Ensures proper corrosion protection

process of bis certification

The BIS certification process for Hexagon Head Screw (Size ranges from M 5 to 64) involves multiple steps, designed to thoroughly evaluate a product's compliance with the required standards. Here is a general overview of the certification process:

Online Registration: Manufacturers register on the BIS Manak Online Portal by submitting company details, factory information, and product specifications. Foreign manufacturers must appoint an Authorized Indian Representative (AIR) in India.
Testing at BIS-Approved Laboratory: Product samples are tested in BIS-approved laboratories to evaluate electrical safety, insulation resistance, heating efficiency, durability, and overall performance as per requirements.
Application Submission: The application is submitted along with laboratory test reports, technical documents, manufacturing process details, and factory information. Foreign manufacturers must also provide AIR-related documents.
Factory Inspection: BIS officials conduct an on-site inspection of the manufacturing unit to verify production processes, quality control systems, safety measures, and compliance with the standard.
Grant of BIS License: If all requirements are successfully met, BIS issues the certification license under Scheme-I, allowing the manufacturer to produce and sell certified products.
Use of ISI Mark: After certification approval, the manufacturer is permitted to use the ISI mark along with a CM/L number on the product, confirming compliance with the standard.
