ISO 4014 is an international standard that sets guidelines for Hexagon Head Bolts - Product grades A and B. These bolts are commonly used in various industries for their strength, durability, and resistance to corrosion.
The standard defines the dimensions, mechanical properties, and tolerance requirements for hexagon head bolts made from carbon steel and alloy steel. The bolts are further classified into two grades - A and B, based on their tensile strength, yield strength, and elongation.
Grade A hexagon head bolts are made from low carbon steel and have a minimum tensile strength of 400 MPa. These bolts are suitable for general purpose applications that do not require high strength. On the other hand, Grade B hexagon head bolts are made from medium carbon steel and have a minimum tensile strength of 830 MPa. These bolts are commonly used in structural and heavy-duty applications that require high strength.
The standard also specifies the manufacturing process, testing procedures, and marking requirements for hexagon head bolts. The bolts must be made from high-quality steel and must undergo various tests, such as tensile testing, hardness testing, and dimensional checks, to ensure their compliance with the standard.
One of the critical factors in ensuring the reliability and durability of hexagon head bolts is their surface finish. The standard specifies the surface finish requirements for hexagon head bolts to prevent corrosion and improve their appearance. The bolts must be free from defects such as decarburization, scale, and cracks.
