EN 1092-1 Bolt length EN 1092-1 Bolt length XL83NL (Mechanical) (OP) 3 Oct 12 12:45 Does anyone knows where in EN1092-1 the minimum required bolt length is treated? Or is bolt lengths discussed in construction codes that reference to EN1092-1?

Best Regards Qalander(Chem) RE: EN 1092-1 Bolt length XL83NL (Mechanical) (OP) 16 Oct 12 08:29 Thanks, but your reply didnt answer my question. Im looking for bolt lengths, especially where they're specified in EN1092-1. Perhaps EN1092-1 doesnt specify anything on that, which makes the answer a simple 'No'. Perhaps a construction code referencing to EN1092-1 specifies bolt lentghs? RE: EN 1092-1 Bolt length TVP (Materials) 16 Oct 12 12:40 I am not sure where bolt length is discussed, but it is not in EN 1092-1. The bolt diameter and number are shown in the various tables, as is the height/thickness of the flanges, but nothing specific on bolt length. RE: EN 1092-1 Bolt length XL83NL (Mechanical) (OP) 16 Oct 12 13:21 TVP, so far Ive figured that out too. Perhaps a construction code like EN 13445 (vessels) or EN 13480 (piping) will mention it. I'll check EN 13480.
