willclarke 50 Report post Posted April 7, 2019 Weird one, I need to get a longer bolt of the one circled in the pic below, it's the bolt that the exhaust hanger fixes to the secondary cat pipe. Does anyone know the bolt size / thread / pitch? Tia Sent from my Pixel 3 XL using Tapatalk Share this post Link to post Share on other sites
vanko25 70 Report post Posted April 7, 2019 It looks like a 8mm bolt to me. If the head size is 12mm it is 100% 8mm bolt according to the JIS standard. You will be able to find some bolts in Screwfix or ToolStation which are 8mm but with 13mm head as we use the ISO over here. Preferably look to get high tensile bolt. Also look at the attached table for reference. Hope it helps! 1 willclarke reacted to this Share this post Link to post Share on other sites
willclarke 50 Report post Posted April 7, 2019 Thanks, looking at the thread pitch/angle mainly as not as easy to measure, to make sure don't cross thread the hanger nut! (ha oh dear) Sent from my Pixel 3 XL using Tapatalk Share this post Link to post Share on other sites
vanko25 70 Report post Posted April 7, 2019 I think that should be standard thread pitch. At least the bolts that connect the mid pipe and the 2nd cat originally are 8mm with 12mm head with standard pitch. Don't over think it Buy few sizes bolts i.e. 8mm/13mm head and 10mm/17mm head if you are unsure what size the bolt will be. Then just try to screw the bolt on the hanger nut by hand if it goes easily it would be okay. 1 willclarke reacted to this Share this post Link to post Share on other sites
