Yes, I'll be using M6 Rivnuts. The Rivnut are a fixed length as far as I'm aware, although I would approximate 10mm deep when compressed. For the bolts, I haven't done the work or even obtained the bolts yet. I plan to be using some around 15-20mm long, as there's no real reason for them to be longer unless they're being used as studs.
I've tried installing a couple of Rivnuts on a scrap piece of Aluminium. The correct tool is essential. I tried one with the tool and one without; the latter being impossible to stop the Rivnut from spinning. The tools are readily available from eBay etc.
Thank Matt. I watch a YouTube vid and it was apparent the tool was essential. About £12 and upwards on ebay.
I also looked at aluminium nuts and self locking bolts but I would have to be sure I (or a helper) can get access and hold the bolt head.
I also found these "16mm 19mm 29mm, BONDED TEK SCREW ALUMINIUM ROOFING WASHERS, EPDM RUBBER" http://www.ebay.co.uk/itm/16mm-19mm...hash=item19fe94a720:m:mMQfaYSFutWEMiOE5B2bUfQ They seem idea for spreading the load on the aluminium heat shields but will need to check for clearance. The shields feel very flimsy.
