DIN stands for Deutsches Institut für Normung (German Institute for Standardization) and this Standard is frequently used – and even recommended – in the Netherlands. There are more than 400 DIN standards for fastening material and approximately 100 DIN standards for screw thread. These standards provide transparent technical information for both the supplier and the customer and serve as a means to prevent any misunderstanding about the product to be delivered. A product of DIN grade and type, and size, is always the same universally. In additions, there is also the NEN, Nederlands Normalisatie Insitutut ( Netherlands Standardization Institute) standard and the ISO (International Organisation for Standardisation) standard, whereby the ISO standard often concurs with a DIN standard.
