jj48 Posted April 1, 2009 Share Posted April 1, 2009 Hi Trevor, a rivnut is basically a nut that is locked in position by compressing a shoulder to lock the nut into place. I use them where access/space is poor and it makes for a more professional looking finish. Wurth now do a "riv bolt".

dreamer_uk75 Posted April 1, 2009 Share Posted April 1, 2009 I think of them like rivets with a thread. You make a hole (e.g. in the bodywork) and pop the rivnut in with a special gun thing. The rivnut is a tube with a thread. Then you can screw a nut or screw into it and it's secure, without needing a nut at the other end. Idea for rear wings which are either fiddly or difficult to get to the other side to put a nut on. I just bought a rivnut gun from RS Components - they aren't cheap though!

jingars Posted April 1, 2009 Share Posted April 1, 2009 The budget rivnut kit on the Car Builder Solutions website has a little diagram that helps. Link to comment Share on other sites More sharing options...
Trevor Gilby Posted April 1, 2009 Author Share Posted April 1, 2009 So has anyone bought and used the budget kit, and if so is it a good bit of kit. I want to fix new rear wing protectors to the rear wings (obvious 😳). Link to comment Share on other sites More sharing options...
Support Team Shaun_E Posted April 1, 2009 Support Team Share Posted April 1, 2009 I have the cheap CBS one and it works fine. However it's not that robust and if you squeeze too hard you could damage the threads on the tool. For occasional use it is great. I wouldn't recommend using rivnuts to fit wing protectors as the protector will end up standing slightly proud of the wing allowing dirt and grit to get between the wing and protector. Normal rivets are the best way to secure wing protectors although I have seen them glued!

jingars Posted April 1, 2009 Share Posted April 1, 2009 I bought a really cheap one off ebay to replace my rear wings after an 'incident' with a cone at Donington. If you are just doing the wing protectors, shirley you just want to pop-rivet them? Link to comment Share on other sites More sharing options...
Paul Deslandes Posted April 1, 2009 Share Posted April 1, 2009 1/8th diameter poprivets for protector panels. Rivnuts + bolts are for holding the wings onto the car. If you buy new stainless panels from CC they'll provide you with new rubber strip and enough (just) poprivets to do the job in the pack. Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted April 1, 2009 Leadership Team Share Posted April 1, 2009 Small size rivnuts (eg. M3 or M4) should be fine for wing protectors. Normally ordinary rivets but there's really no reason why rivnuts would not do a good job and make the protectors more easily removeable/replaceable. The head of the rivnut will be absorbed in the compression of the rubber trim strip so will not be noticeable. With CF protectors I normally add a couple of small spacing washers between the protector and wing otherwise the protector is pulled "into" the trim strip compromising the fit. SS protectors are stiffer and don't need the washers. Stu. Link to comment Share on other sites More sharing options...
jingars Posted April 1, 2009 Share Posted April 1, 2009 Interesting points, Stu. So do you use something like a rounded head bolt with a hex fitting for a resonable looking finish? Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted April 1, 2009 Leadership Team Share Posted April 1, 2009 I've only fitted cf protectors with rivets ......... but I did use "mushroom" head set screws when replacing the rivets on a scuttle/bulkhead join with bolts/rivnuts. M4s are probably the ideal size, M3s are VERY small! Stu. Link to comment Share on other sites More sharing options...

Trevor Gilby Posted April 1, 2009 Author Share Posted April 1, 2009 Thanks one and all, and especially Stu, and Phil who emailed me. I particularly wanted to be able to remove the protectors. Stupid thing really, I want to get the whole car resprayed by TSK, but not now until the end of the wonderful spring and summer months we are about to get . I have had the Millwood wrap aroun protectors for around six months now and want to get them on the car sooner rather than later as the existing s/steels look a bit tired and the wrap around will hide a fair bit of rash on the existing wings for the time being. Just need Stu to explain a bit mor re spacers and positioning etc if you could email me direct it would be great Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted April 1, 2009 Leadership Team Share Posted April 1, 2009 IIRC the Millwood protectors are shaped and quite a close fit - may be better to bond on (although that would cause problems removing!)?
