mattross1313 Posted February 11, 2014 Share Posted February 11, 2014 Morning all, Looking for advice off you tech guru's. I am looking to source some bolts for a DE engine block (pic below with a square around the ones I need). After a Googling session last night I have landed on these bolts being M11 with 1.25 pitch? First off is M11x1.25 the correct size? Second up, I am looking for 4 'spare' bolts of this size. Anyone have some laying around? (they will get powder coat on them so they will most likely be no good once I am finished with them. Thirdly, I am looking to get some nice chrome/stainless bolts to thread into these holes but struggling with the M11 size. (don't worry the engine is not going back in a car). With this M11 restriction on finding 'nice' bolts, would it be less hassle for me to just re-thread this out to an M12? Thus providing me much more choice of bolts? Apologies for the ramble Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted February 11, 2014 Share Posted February 11, 2014 Plenty preowned OEM bolts in stock. Just drop me a PM if I can help further. Alex. Quote Link to comment Share on other sites More sharing options...
mattross1313 Posted February 11, 2014 Author Share Posted February 11, 2014 Cheers Zman Might end up re tapping these up to an M12 as there are bolts a plenty in that size. Just found these on ebay at a good price http://www.ebay.co.uk/itm/M12-12mm-A2-STAINLESS-STEEL-SOCKET-CAP-SCREWS-ALLEN-KEY-BOLTS-HEX-HEAD-FWS-/200831988865?pt=UK_DIY_Material_Nails_Fixing_MJ&var=&hash=item2ec284f481 Quote Link to comment Share on other sites More sharing options...
Briggsybriggs1 Posted February 11, 2014 Share Posted February 11, 2014 If you are fitting new bolts make sure they are metric fine Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Keyser Posted February 11, 2014 Share Posted February 11, 2014 (edited) May be worth pointing out - these bolts are not to hold the head on Edited February 11, 2014 by Keyser Quote Link to comment Share on other sites More sharing options...

Ridz Posted February 12, 2014 Share Posted February 12, 2014 Retapping from M11 to M12 is probably not the best course of action. It is considered good engineering practice when retapping to increase thread size by at least 2mm. Suggest you replace like for like, if possible, and if they are not stressed components, eg head bolts, then ZMANALEX is your man! Quote Link to comment Share on other sites More sharing options...
mattross1313 Posted February 12, 2014 Author Share Posted February 12, 2014 Thanks guys been speaking to Alex over PM for some other items but hopefully all sorted now. As hinted to above this will end up as furniture so will not be under much stress. I ended up solving the issue today as it turns out I need to use a smaller bolt anyway, oops! Thanks for replies though - once complete I will be along with pics Quote Link to comment Share on other sites More sharing options...
