The Fastener Dimension Guide is a web application that allows you to find bolt dimensions directly from your mobile device. Simply enter the bolt size and length and you will be presented with dimensions that conform to ISO standards.
The Fastener Dimension Guide allows you to select between the following ISO standards: ISO4014 (DIN 931), ISO4017 (DIN 933), ISO4032 (DIN 970) and ISO4762 (DIN 912). If you are working with steel construction fasteners you can select either EN 14399-3 for HR fasteners or EN 14399-4 for HV fasteners.
