STANDARDS - ISO / BS / DIN

DIN is the acronym for ‘Deutsches Institut für Normung’, which is the ‘German institute for standardisation’ who developed detailed technical standards for the engineering industry, amongst many other industries.  With reference to fasteners, DIN number indicates the that the part conforms to a specific metric standard.

The International Standards Organisation (ISO) standard has evolved to supersede the DIN standard, which was historically the predominant metric fastener system referred to.  The intention of the ISO standard was to standardise the technical specifications worldwide to simplify the system and aid the flow of trade via a universally recognised standard.

In practice, DIN and ISO standards are still both commonly used when specifying fasteners and both standards are recognised by Technifast when our customers specify the fasteners they require.

The chart below shows the ISO standards and their equivalent DIN and BS standards.
