wfarrell Posted April 16, 2003 Share Posted April 16, 2003 7'ers, I'm racing this year and don't want to have the hassle of repairing ripped out riv-nuts and body work when (not if!) i lose a rear wing. Can anybody recommended a suitably 'snappable' plastic bolt supplier ? I've heard another good idea is to under-cut the bolt head with a stanley knife to create a stress-raiser - any thoughts ? Cheers all - Will Link to comment Share on other sites More sharing options...
KayTee Posted April 16, 2003 Share Posted April 16, 2003 Hi ! I have put together a complete kit of rear wing fasteners. Using Polyamid bolts when attaching the rear wings makes sure that these shear upon contact, instead of pulling the rivnuts and the surrounding aliminium skin out. Now, to give you moe versatility when fitting the wings to your liking, how about this: - 15 Polyamid M5 bolts of sufficient length (M5 x 20 or 25) (4-5 used to attach one wing) - 20 stainless steel 5 x 30 load-spreading washers - 15 stainless steel self-locking nuts, M5 - 10 RivTi-flex neoprene self 'clamping 'rivnuts', vibration absorbing, stainless steel thread portion, as seen here: here This way, one can - use the original M5 rivnuts already in place using Poly bolts - drill 5mm holes, and use Poly bolts, load-spreading washers and stainless self-locking nuts - slightly enlarge previous rivnut holes (if needed) and use RivTi-flex, no need for special tools and reducing transmition of vibrations, no corrosion, tracelessly removeable - a mix of above options (RivTi-flex in inaccessible areas, washers in accessible places) Picture of the kit: here All this, including postage, for 9 quid. Payment through PayPal, for example. Sounds OK ? If you want to go ahead, please get in touch by direct e-mail to: KT(at)Kay-Tee.de Regards - Karsten Edited by - KayTee on 10 Jul 2004 12:16:21 Edited by - KayTee on 4 May 2005 08:44:25 Link to comment Share on other sites More sharing options...

Sheds Moderator Posted July 8, 2004 Share Posted July 8, 2004 Another vote for Karsten, this kit works well even in my car, where the sides are scarred by ripped out rivnuts. Yes, you can DIY but the little rubber shrouded nut things that he includes in the kit are not easily available. They are much better than rivnuts and you get a nice solid fixing. You don't need a tool to fit them, they fit irregular holes, and if you ever rip them out there is no (or less) damage to the panel. One word of caution - do be careful not to overtighten the nylon bolts, they are only nylon, and the fact that you can hang a wing on 2 selftappers does not mean that the nylon bolts will be as good. Take your time and use plenty of the fixing holes. If you are lucky enough to have a car with unscarred skins, so much the better. You have more chance to hang the wing on several bolts, which helps get a good fit. Link to comment Share on other sites More sharing options...

Paul Bowden Posted July 8, 2004 Share Posted July 8, 2004 Freestyle also will supply these bolts, and you get a freestyle sticker with your order. I have also tested these bolts, and they do stop you losing your riv-nuts 😬 Link to comment Share on other sites More sharing options...
christian.v Posted July 8, 2004 Share Posted July 8, 2004 Thanks guys, the solution was found at my local tool shop, which stocks M5 nylon screws etc Link to comment Share on other sites More sharing options...
KayTee Posted July 8, 2004 Share Posted July 8, 2004 *Mine* are Polyamid, not poxy Nylon Freestyle: Wonder where they got the idea from I proposed the use of Poly bolts to Caterham's Tech Dept quite some time before a certain someone went and started a seperate business. Now, what does interest me: what exactly does their kit consist of ? I could be tempted to throw-in POP Rivet stickers, afterall, that's what holds it all together 😬 Edited by - KayTee on 8 Jul 2004 19:39:35 Link to comment Share on other sites More sharing options...

Lennie Posted July 10, 2004 Share Posted July 10, 2004 Kay - Tee for your information plastic wing bolts were used on the factory race cars when the race series started in 88, and were fitted by most of us racing back in though days. Also I believe James Whiting has been suppling those kits for quite some when did you submit the idea to the factory as I do not remember you talking to me.

KayTee Posted July 10, 2004 Share Posted July 10, 2004 Hello, Len ! Thanks for clearing this up. I wonder why these haven't been offered to road/track day users ? Well, repairs are a business, too. Either way, I have no idea when I sent that e-mail to CC. It must have been three or four years ago. I just checked, my Paypal account has been active since 09.2001, it must've been about then that the idea of the kit was developed on the Se7ens listc Before then a few people received just the Poly bolts upon request. Who was first or not doesn't matter to me, you can have the Laurels if you wish. What matters to me is that fellow Se7eners can use their cars as designed without fearing massive repair bills upon light contact with cones or similar.

KayTee Posted January 6, 2005 Share Posted January 6, 2005 Sorry, Roger, I have been having PC problems yet again, hopefully now solved with a new machine. Please mail again and I'll get you sorted.

stevefoster Posted January 7, 2005 Share Posted January 7, 2005 Don't use all the bolts. You may still get ripped rivnuts. I used 4 in each rear wing and had no probs with them staying on. Another option is industrial velcro... works very well.
