does anyone agree or disagree??
if partial recoignition is requested then whats stopping mra-minis receiving recoignition as nobody knows who is the originator of this topic and everyone else has so called STOLE THEIR INFO, its a childish thing to ask for recoignition on something thats probably going on generations.... "topic closed"
thank you mra-minis for resurrecting this topic as i didn't know about it and to the members who have contributed information as they have been very helpfull.

Like Martin, Sprocket is a very knowledgeable and long standing TMF member. His expertise, particularly on the mystical wonders of Rover fuel injection, has benefitted many. If he's about less frequently on the forum than he used to be it's because of the petty spats.

You're saying MRA stole your information to post it on here so he can sell some bolts?
Your words not mine!!!

I note that in Mini magazine February issue page 106 a certain so called specialist who has told me he now uses the correct bolts has a photo of a CSM with SAE 5 bolts instead of SAE 8's.
So who's right ?

http://www.engineersedge.com/hex_bolt_identification.htm covers head markings etc.
http://www.americanfastener.com/technical/grade_markings_steel.asp more of the same, including nuts.
http://store.curiousinventor.com/guides/Metal_Working/Screws/ some good technical stuff.
www.cat.com/cda/files/87031/7/13_OSS_Hardware.pdf A useful catalogue with dimensions. I can't seem to get rid of the italics. Grrrrrr!
http://www.rigging.net/Bolts.html More head markings, tables, dimensions.
http://www.jgmes.com/library/table_fastener.htm Good comparison of US (SAE) and ISO standards, and a dire warning about inappropriately plated bolts. The dreaded hydrogen embrittlement!
http://www.britishfasteners.com/BRITISH_SERIES_BOLT_HEADMARKINGS.pdf Some nice pictures of head markings and also shows that "Grade S" used on early Minis is comparable to "Grade 8.8".
http://panchsheelfasteners.in/product_pdf/hightensile_bolts_technical.pdf Again relates grades S and V to ISO standards and gives things like recommended torques for different sizes. (If Rover have recommended a torque, use that of course).
http://www.bestbolt.com/white_papers/white_paper_02.pdf How to match strength of nut and bolt, which is actually quite important.
I hope these links are useful. You may care to print out your favourite, e,g, a torque chart, laminate it and keep in in the garage for reference. Comments and additions are of course welcome.
