Product Description

DIN 5903-1 - 1997 Fish Bolts - Part 1: with Round Head and Oval Neck

There are no limitations for different standards, types and modifications of Bolts as per particular applications. DIN Bolts are available in a wide range of German Standards. DIN Bolts are often made of steel alloy or stainless steel because of strong metal and for used in any type of environment. In addition, DIN Bolts are available with different types of coating or plating to enhance the corrosion resistance and appearance.

Leader-Fastener® DIN 5903 Round Bolt has a hex head and coarse or fine machine screw threads. Select from partially threaded or fully threaded. All short lengths are fully threaded; for partially threaded the minimum thread length is longer for larger bolt sizes. JIS B1180 and three sizes of ISO 4014 and ISO 4017 have heads that are smaller than their DIN counterparts. Steel, from Class 8.8 to 12.9, and stainless steel are available as are plain and zinc plated finishes. To differentiate between partial and full threads, we classify Hex Head Bolts as partially threaded and Hex Head Cap Screws as fully threaded. Hex Head Bolts are also called Machine Bolts.
