Hi Folks, I got fed up ordering a "special bolt" for £3 or £4 quid a time to find a bog standard bolt arrive :doh: worth about 50p, so I went looking and found this chart for breaking down bolt/fastners part numbers in to plain speak.

Remember sometimes you do need to use High tensile bolts, but at least with the info above you can still get the High Tensile bolts a lot cheaper from any engineering supply shop.

Hope this is of use, and let me know if you find out any of the info is wrong or needs added to.

Sorry had to zip file to make it upload
