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

Hexagon head screws are essential mechanical fasteners used across construction, automotive, electronics, industrial machinery, and infrastructure sectors. These screws require precise dimensional accuracy, mechanical strength, and corrosion resistance. In India, the manufacturing and sale of such screws is regulated under IS 1363 (Part 2):2018, and BIS certification is mandatory for compliance.

This blog explains the BIS certification process for hexagon head screws, highlights why ISI marking is legally required, and shows how Standphill India ensures you meet all BIS compliance standards.

What is IS 1363 (Part 2):2018?

IS 1363 (Part 2):2018 specifies the requirements for hexagon head screws with product grade C, including:

Nominal thread diameters (M5 to M64)

Mechanical properties (tensile strength, proof load)

Dimensional tolerances for head, thread, and shank

Surface finish, plating, and corrosion resistance

Marking and packaging specifications

This standard is in line with international ISO norms and ensures the fasteners meet functional and safety expectations across applications.
