rutthenut Posted June 2, 2013 Share Posted June 2, 2013 Having some difficulty with my nuts ... Using either a 22mm socket, or a cross-type wheel brace, I find that the socket doesn't quite fit into the recess in the GT/E alloy wheels. Some nuts are easy enough but others near impossible to tighten properly. What's the solution? Smaller nuts, longer nuts, or slimmer socket? Don't have a standard Manra toolkit for comparison. Thoughts, suggestions? Quote Link to comment Share on other sites More sharing options...
spiney_norman Posted June 3, 2013 Share Posted June 3, 2013 Never had a problem myself, but 22mm doesn't sound right. Thought they were 19mm nuts? Quote Link to comment Share on other sites More sharing options...
rutthenut Posted June 3, 2013 Author Share Posted June 3, 2013 (edited) Never had a problem myself, but 22mm doesn't sound right. Thought they were 19mm nuts? Ah, so my nuts are too big? ;-) Will do a search but anyone know off-hand what the stud diameter/thread is on the Manta? Edited to Add: Opel GT forum describes those older items as M12 x 1.5 and M12 x 1.25 - not sure which is right. Found an eBay listing for some alloy nuts to fit the Manta, which are M12 x 1.5, so is that the correct size? Those happen to be 17mm nuts, in alloy, fwiw.

Manta again Posted June 3, 2013 Share Posted June 3, 2013 I agree with spiney the head of the bolt is 19mm, not sure of thread pitch, but wouldn't fancy alloy wheels either way. Quote Link to comment Share on other sites More sharing options...
tony g Posted June 3, 2013 Share Posted June 3, 2013 Pitch will be 1.5 Tony 1 Quote Link to comment Share on other sites More sharing options...

Alloy wheels, or alloy wheel nuts? I don't want lightweight alloy nuts - prefer simple steel ones (don't even car for chrome) and better still if open rather than closed. This is on a rally car, so robust fittings more of a preference to shiny or lightweight parts... Quote Link to comment Share on other sites More sharing options...
rutthenut Posted June 3, 2013 Author Share Posted June 3, 2013 Thanks for confirmation - will just order some new wheel nuts, M12 x 1.5mm, with 19mm head, so expect normal wheelbrace/socket to fit without contact with alloy wheel centres. Do not like the idea of my nuts coming off if not tightened properly! Quote Link to comment Share on other sites More sharing options...
Manta again Posted June 3, 2013 Share Posted June 3, 2013 Yeah , sorry meant wouldnt want alloy wheel bolts, alloy wheels are essential. 1 Quote Link to comment Share on other sites More sharing options...

rutthenut Posted June 4, 2013 Author Share Posted June 4, 2013 Thanks. Further confirmation of the right parts. I tend to use Demon Thieves or JJC for various bits, though have used Rally Design before. Ordered mine from DT as I needed some other motorsport parts from them. Also get 10% discount there :-) Cheers all Quote Link to comment Share on other sites More sharing options...
