Hexagon Head Bolts (IS 1363-1)
Equivalent Standard: ISO 4016
Hexagon head bolts, screws, and nuts of product Grade C are essential fasteners widely used in structural, mechanical, and general-purpose applications. These components are designed with a hexagonal head for easy wrench application and feature robust threads to provide strong connections.
Covering a size range from M 5 to M 64, these fasteners are suitable for medium-strength assemblies and offer reliable performance under varying load conditions. Grade C products are ideal for non-critical applications requiring durability and cost-effectiveness without compromising on functionality.

IS 1363-1
IS 1363 was originally published in 1960 and first revised in 1967. Subsequent to the publication of 1967 edition, many changes had been agreed upon at international level which have been reflected in IS 1367 series of standards covering ‘Technical supply conditions for threaded steel fasteners’. Accordingly, the second revision was published in 1984 splitting the standard into 3 parts covering hexagon head bolts IS 1363.
