68vitesse Posted August 25, 2016 Report Share Posted August 25, 2016 Bought studs from the supplier mentioned in a recent post and found that with steel wheels the threaded portion is to short. Do not feel like extending the thread as cut with a die will be weaker than the original rolled thread. Regards Paul Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 25, 2016 Report Share Posted August 25, 2016 good point guess most are on alloys with thicker nave, so we need to sort out some pretty much full threaded ones Pete Link to comment Share on other sites More sharing options...
68vitesse Posted August 25, 2016 Author Report Share Posted August 25, 2016 Well back in the garage to put things back as they were, only mid to high twenties. Time not a problem as retired. Regards Paul Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 25, 2016 Report Share Posted August 25, 2016 would a set of wheel spacers get it clamped as a option 12mm are far better studs but no good if the nuts bottomed out on the thinner metal wheels needs some homework here Pete Link to comment Share on other sites More sharing options...
rogerguzzi Posted August 25, 2016 Report Share Posted August 25, 2016 Hello Paul How about some longer nuts that have a small amount of thread removed from inside stud end? As Pete says they far superior to the 3/8" ones(the ones I fitted are marked 10.9 so are high tensile) and if they hold Range Rover wheels on with 5 and they are huge and weighs tons I think we will never break any on our cars! Roger or alloy wheels? Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 25, 2016 Report Share Posted August 25, 2016 you need something like triumph 2000/2500 front is short rears are longer eg http://www.rimmerbros.co.uk/Item--i-136860 but this is 7/16" unf not metric just an idea Link to comment Share on other sites More sharing options...
Colin Lindsay Posted August 25, 2016 Report Share Posted August 25, 2016 Standard studs are adequate for standard i.e. steel wheels; it's only when you go for thicker wheels that you really need the thicker or longer studs. As 68vitese has found, fitting longer studs with standard wheels causes its' own problems as the nuts won't tighten sufficiently, and you're now into the realms of packing and shimming which again can cause even more problems and worry. Standard studs with good threads on both haven't let me down yet. Link to comment Share on other sites More sharing options...
AidanT Posted August 25, 2016 Report Share Posted August 25, 2016 I got mine from jigsaw They have extended length as well as standard in 7/8" worth comparng prices Theirs already have the bevels cut Aidan Link to comment Share on other sites More sharing options...

haggis Posted August 25, 2016 Report Share Posted August 25, 2016 Hi Paul, I converted my GT6 studs to 12mm last weekend, I have fitted some Dunlop D1's from JBW and they come with a tapered nut sleeve with an open thread and an internal hex head fitting. http://www.johnbrownwheels.com/Shop/P-1363-12x1.5mm---Star-Head-Chrome-Wheel-Nut.html Now the internal thread was a little short for the original steel wheels (by about 3 -5mm), obviously perfect on the Alloys, but Im pretty sure they can get them in various lengths. If anyone knows the torque wrench settings for alloys on 12mm studs would be greatly appreciated. Hag Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 25, 2016 Report Share Posted August 25, 2016 around 55- 60 lbft should be fine for 12mm or 7/16unf Pete Link to comment Share on other sites More sharing options...

Nick Jones Posted August 25, 2016 Report Share Posted August 25, 2016 M12 studs as fitted OE on the Land Rover Freelander Mk1 are threaded to the shank and work even with steel wheels. http://sideways-technologies.co.uk/forums/index.php/topic/1239-freelander-wheel-studs-mgf-wheels-on-spitfire/ Nick Link to comment Share on other sites More sharing options...

Clive Posted August 26, 2016 Report Share Posted August 26, 2016 I have ford 12mm studs on the front of my car, and mgf with the mgf hub, on the rear. I use std steels with no issues. Paul, sounds like they are a pattern part, land rover suppliers often offer 3 or more different makes for many parts. Maybe ask the supplier to check stock, and see if another brand is correctly made. I know it shouldn't be necessary, but sadly we live in a world of variable quality parts.

SpitFire6 Posted August 27, 2016 Report Share Posted August 27, 2016 around 55- 60 lbft should be fine for 12mm or 7/16unf Pete Pete, your figures seem rather low for wheel studs. I thought wheel studs n nuts were all higher than 8.8 grade? I'm sure my 12mm nuts are torqued to over 80 Lb/Ft. Cheers, Iain. Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 27, 2016 Report Share Posted August 27, 2016 I based the figure on the 7/16unf on the Triumph spec for big saloons as , 'similar' spec if you search on line 12mm wheel nuts most clues comes around the 55-60 lbft zone you could go higher on modern spigot nuts , but we are still on 60deg cones there is also consideration needed if you have cones or spigot nuts and the type of wheel in use all have a bearing on 'how tight' if 42 lbft is good enough to hold the wheel forces on the 3/8" studs then you can all make a preference for how tight when you upgrade, if you have a nice long tommy bar ok. use 80 but dont let the taper cone deform the naive nut seating by over tightening and spreading the seat. just some thoughts Pete Link to comment Share on other sites More sharing options...
SpitFire6 Posted August 27, 2016 Report Share Posted August 27, 2016 Hi Pete, Thanks for that. I always assumed the 12 mm studs/nuts were 10.9, hence my over 80 ft/lbs torque setting. Cheers, Iain. Link to comment Share on other sites More sharing options...
rogerguzzi Posted August 27, 2016 Report Share Posted August 27, 2016 Hello All My eyes water if tighten my nuts that tight? I have been using 50/55 Lbs/Ft on my Spitfire alloy for about 4+ years the man at tyre place wanted to tighten them to 90/100Lbs/Ft !!!!!!!!!!!!!!!!!!!!!!! and he was quite worried when I said 50/50 Lbs/Ft was ok Roger Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 27, 2016 Report Share Posted August 27, 2016 Ian , im sure theres a better technical result in making a spec to suit our ongoing fettling of the base triumph specification we just dont have the design and experimental depts around us to qualify the brainwaves I do have a torque to yield torque wrench, but the special batteries are well dead and it would be ideal on this sort of analysis , but its well defunct, pete Link to comment Share on other sites More sharing options...
68vitesse Posted August 28, 2016 Author Report Share Posted August 28, 2016 Vitesse steel wheels 38-40 ft/lb alloys on modern about 90 ft/lb as I understand the steel are designed with give at mounting points. Regards Paul Link to comment Share on other sites More sharing options...
dougbgt6 Posted August 28, 2016 Report Share Posted August 28, 2016 Last time I went to the tyre place they put my wheel nuts back on with an air gun. Dumb question, can you set the torque on air air gun? Dumb supplemental question, if they can, do they bother or, just whack it up to maximum?

Pete Lewis Posted August 28, 2016 Report Share Posted August 28, 2016 I have always used event-tyres and they nip with a gun and hand torque after but some are hopeless , you can if you pay a fortune get modern air guns to be torque adjustable, we made leaps and bounds on torque control on truck assy with large supply pipes and short air hoses, , its no use having the pressure if there is no volume to go with it, back in the 80s we and altas copco did a lot of trials , one idea of the day was a rack of sockets which when you pulled a socket off to use on a multi use gun it would change the regulator to give the right torque for the selected socket, some guns would squirt a dab of blue paint on the nut if the correct torque was achieved , i guess things have moved on a long way especially with electric powered portable guns .
