thompster Posted February 17, 2015 Share Posted February 17, 2015 I've bought a fixing pack to go with my 'X' style metric trackday rollbar but the shallow-headed M10 bolts that go up the 'legs' of the roll bar feel quite loose.They screw all the way in but the thread isn't exactly a snug fit and I'm worried they'll strip.Here's what I bought:http://caterhamparts.co.uk/product.php?id_product=4425Any idea if M10 is the correct size for these bolts and if it's normal for the thread to be 'generous'?Thanks, James.

CharlesElliott Posted February 17, 2015 Share Posted February 17, 2015 I don't know about metric, but they used to be 7/16" which =~ 11.1mm.Do you have a 7/16" bolt you can try? Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted February 17, 2015 Member Share Posted February 17, 2015 That fit doesn't sound right.I don't know how many variants there are. Suggest you check with Darren at Caterham if you don't get an answer here. Jonathan Link to comment Share on other sites More sharing options...
thompster Posted February 17, 2015 Author Share Posted February 17, 2015 Charles - thanks for the tip, I'll see if I can lay my hands on a 7/16" bolt - may not be easy though. Good advice re calling up, I'll try and do that tomorrow. Link to comment Share on other sites More sharing options...

thompster Posted February 19, 2015 Author Share Posted February 19, 2015 Ok, so it was me being an idiot. With all this talk of thin-headed bolts going up above the shocks I'd picked the bolts with the thinnest heads in the pack and assumed they were the ones. Having read the manual it looks like the metric chassis uses caphead allen bolts up into the roll bar bushes and those ones fit ok.... Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted February 19, 2015 Member Share Posted February 19, 2015 :-)Please can I have a copy of that manual?Jonathan Link to comment Share on other sites More sharing options...
thompster Posted February 19, 2015 Author Share Posted February 19, 2015 Hi Jonathan, just to follow up on PM.......the manual is on the caterham site here and covers roll bars from page 205. Page 206 says to pass bolt number 3 up into the location bushes, and in the fixing pack (30P010A) bolt number 3 is an M10 x 20 caphead. That's the theory, anyway, but worth noting I've not actually tried it to see if it clears the shock.... Link to comment Share on other sites More sharing options...
