There are a few different bolt ISO standards that apply to bolts, screws and studs made from different materials like carbon steel, alloy steel and stainless steel.
The most common bolt ISO standards are:
- ISO 898-1:2013 - This standard specifies the mechanical and material properties of bolts, screws and studs made of carbon steel and alloy steel used in bolting assemblies. It also specifies the methods for verifying these properties.
- ISO 898-2:2009 - This standard applies to bolts, screws and studs made of austenitic or austenitic-ferritic stainless steel used in bolting assemblies. It specifies the mechanical and material properties of these fasteners, as well as the methods for verifying these properties.
- ISO 3506-1:1997 - This standard applies to stainless steel bolts, screws and studs used in bolting assemblies. It specifies the mechanical and material properties of these fasteners, as well as the methods for verifying these properties.
- ISO 3506-2: Corrosion-resistant stainless steel fasteners
- ISO 965-1: General table of tolerances
- ISO 1042: Chemical analysis of steels
How do you know if a bolt is a standard?
There are a few ways to tell if a bolt is a standard. One way is to look for the manufacturer's name or logo stamped on the bolt.
Another way is to look for a head-mark, which is a raised or incised symbol on the bolt head that indicates the standards organisation that has recognised the bolt.
Finally, you can look for the grade mark, which is a letter or numeral stamped on the bolt head that indicates the bolt's tensile strength.
What are ISO standards for fasteners?
ISO standards are a set of international standards that cover the dimensions, properties, and methods of testing for fasteners such as bolts, screws, and nuts. These standards are developed by the International Organisation for Standardisation (ISO), a worldwide federation of national standards bodies.
These differ from DIN numbers on bolts.
What are the benefits of using bolt ISO standards?
Using bolt ISO standards helps ensure that bolts are manufactured to a consistent quality and size, which can facilitate interchangeability between different brands and types of fasteners. Additionally, bolt ISO standards help ensure the safety of users by providing guidance on proper installation and use.
Bolt standards for BZP bolts
There are also bolt ISO standards for BZP bolts, which are a type of bolt coated with a layer of zinc to protect against corrosion.
These standards include;
- ISO 888: Surface roughness
- ISO 10683: Dimensions of bolt heads and nuts
- ISO 10684: Hexagon head bolts
By adhering to these bolt ISO standards, manufacturers can ensure that their products meet the requirements for quality, safety, and durability. Additionally, these standards help to ensure that bolts are interchangeable between different manufacturers and can be used in a wide range of applications.
