Alex Wong1697456877 Posted September 2, 2005 Share Posted September 2, 2005 I don't know. I would guess that safety isn't an issue but I can't say I know - but I do remember something in the blue book about wheel nuts. I guess it's not relavant if you're not competing.

rgrigsby Posted September 2, 2005 Share Posted September 2, 2005 Your right Alex just looked in the blue book, L10.5.3 "must have nuts securing road wheels, except those of a centre lock type, of steel and in thread contact over a minimum length of 1.5 bolt/stud diameters. Extended or composite wheel bolt/studs are prohibited" Guess that rules out Ti and CF 😬 Rob G www.SpeedySeven.com Link to comment Share on other sites More sharing options...
Phil Posted September 2, 2005 Author Share Posted September 2, 2005 OK. That sucks, well spotted, think I will still get some for road use. I think titanium is just as strong as steel if not stronger. X/FLOW 1700 DD 1990 ROAD USE ONLY..SO FAR Link to comment Share on other sites More sharing options...

Pierre Gillet Posted September 3, 2005 Share Posted September 3, 2005 I am interested in the tuner type (the one with the internal allen key). Pierre Link to comment Share on other sites More sharing options...

Phil Posted September 3, 2005 Author Share Posted September 3, 2005 Ok, just weighed the slim style nut with internal allen key hole 12mm. Original nut 53.5g Titanium nut 20.4g T/slim/style 16.6g Would anyone like pics? akapmr@aol.com X/FLOW 1700 DD 1990 ROAD USE ONLY..SO FAR Edited by - phil on 3 Sep 2005 13:00:09 Edited by - phil on 3 Sep 2005 13:31:20 Link to comment Share on other sites More sharing options...

rj Posted September 4, 2005 Share Posted September 4, 2005 I don't think the socket diameter will be an issue even with the new style R3-4-500 wheels. As far as I remember the nuts for these still will be 19mm hex, whereas these are 17mm. Worst case you can use a deep socket. I would never go for the internal allen key type, based on my experiences in the industry (not automotive!) What conserns me is however a company that claims it's nuts to weigh 1/10, when this actually is quite far from the mark. Would they know what they are doing, or are they just show-off's? /r Link to comment Share on other sites More sharing options...
Phil Posted September 4, 2005 Author Share Posted September 4, 2005 RJ, good point on the weight thing. I have the R3/4/500 wheels in 15 inch but I still use the original steel nuts which are 19mm. They kindly sent me a sample of both and I have fitted both and if you email me I will send you some pictures.

Pierre Gillet Posted September 4, 2005 Share Posted September 4, 2005 Thanks Phil for the photo. The slim, allen print nut has a 18 mm thread . Since the stud diameter is 12 mm, the nut thread is exactly 1.5 time the stud diameter. It's OK for steel. Would it be be OK too for titanium ?

rj Posted September 4, 2005 Share Posted September 4, 2005 I'll ask someone whom I'd recon know what he's talking about. He works with car approval. I'll probably neger gat a "proffesional" statement from him, but his opinion is worth listening to anyway. As soon as I know anything, I'll post. Phil, are you still using your 19mm key for the titanium nuts? On the web page they are said to be 17mm hex I would be interested in seeing these nuts, could you email a picture to tlt at rj.dk? /regin Link to comment Share on other sites More sharing options...

rj Posted September 4, 2005 Share Posted September 4, 2005 Thanks Phil, There is no doubt that if I were to fit any of these it would be the "std" style I'd go for - both to make sure that I can tighten it properly - and untighten ! - and because the larger diameter makes force better distributed - sorry don't know the correct English term. A shear will always be in 45 deg, hence, if the OD of the slim one is 18mm this leaves about 3mm wall thickness, if the key with of the other one is 19mm and you have the collar in addition to this, then you have a much longer part of the nut contributing as a "structural member". Looking at the picture, the max OD of the std item is approximately 25 mm, leaving a wall thickness of 6,5mm, hence the structural member is more than twice as long too.

Phil Posted September 4, 2005 Author Share Posted September 4, 2005 Just incase, I find a lot of people unaware that wheel nuts should not be done up very tight, it is natural to do them as hard as possible but it is wrong. If there is an expert anyone can talk to this question will be a good one to ask. X/FLOW 1700 DD 1990 ROAD USE ONLY..SO FAR Link to comment Share on other sites More sharing options...

Pierre Gillet Posted September 4, 2005 Share Posted September 4, 2005 Yep, but actual torque may be somewhat different if the stud is lubricated... Pierre Link to comment Share on other sites More sharing options...
Phil Posted September 5, 2005 Author Share Posted September 5, 2005 I always lube the thread but not the face, do you think this is wrong? X/FLOW 1700 DD 1990 ROAD USE ONLY..SO FAR Link to comment Share on other sites More sharing options...
Pierre Gillet Posted September 5, 2005 Share Posted September 5, 2005 I would say that you are correct Phil. Tell me Phil, what would be the price of 16 normal titanium nuts ? Cheers, Pierre Link to comment Share on other sites More sharing options...
Phil Posted September 5, 2005 Author Share Posted September 5, 2005 They are advertising at £3.50 each at present and I am trying to get a better price, I do need a few more people to show an interest to do this. I have three friends with Nissan Skylines and they all use these on and off the track. X/FLOW 1700 DD 1990 ROAD USE ONLY..SO FAR Link to comment Share on other sites More sharing options...
jerrypike Posted September 5, 2005 Share Posted September 5, 2005 wonky custard i got my wheeels/nuts from caterham- 2 were so incorrectly sized i had to buy 2 more. both the head and shaft were 1mm too big. then had 1 shear off at the head/shaft connection when checking the torque before heading out on track (with a torque wrench 😬) jerry Link to comment Share on other sites More sharing options...
Pierre Gillet Posted September 6, 2005 Share Posted September 6, 2005 I am surprised that so little people are showing interest for these splendid titanium nuts. In the past ali nuts got huge interest although it was necessary to use longer wheel studs ! Pierre Link to comment Share on other sites More sharing options...
John Howe Posted September 6, 2005 Share Posted September 6, 2005 Might get as little more attention if it was reposted under a new banner suggesting it was a bulk buy and stating a price JH Deliveries by Saffron, the yellow 230bhp Sausage delivery machine Link to comment Share on other sites More sharing options...
