Hi, I'm looking for 9 of the tall/fine thread M8x1.0 nylocs for the L-series gearbox covers. I've checked all Ferrari plus nut and bolt suppliers and other usual places. Has anyone found these or have some spare? Seems later cars didn't use these and they were not used on other Ferrari models, I even went through all the Ferrari part# listings for nuts. At this point I don't care about the yellow insert! Thanks, Andrew
Newco do not sell small orders....so you can forget about them unless you want to spent big bucks on nuts and screws etc...
Andrew, those nuts are indeed very difficult to find and new production ones have rounded corners while the originals had nicely defined flats on the hex face. That said I did have a root around and turned up exactly 9 original ones (yellow insert and all) freshly plated and ready to install. Send me your address via PM and I'll shoot them in the mail for you Image Unavailable, Please Login
For my own personal needs, I've been on a quest to locate hardware instead of buying from Ferrari. That quest is yielding some great results. One criteria is to locate non - China hardware which can be difficult especially for nylon insert lock nuts. That all said, we have some stuff in the works
As Rob said, even if you can find a nyloc in the grade, finish and correct yellow insert, it's unlikely to be the same as the original type due to the more rounded corners in later manufacturing. I've found almost all of the nyloc sizes on a Dino but boxes sit on the shelf because they don't look correct for restoration. So salvaging nylocs from other vehicles and cleaning/replating is the way to go IMHO. Buying the odd one from Ferrari is pretty cheap, at least you'll get the correct grade with a yellow insert. It's only nylocs that are a problem, all other nuts, screws and bolts I've generally been able to find new and replate some in the correct finish.
Yes, but I was wondering how they are doing it with the insert in place. Perhaps it's mechanical plating and not electro plating.
Sorry, I'm not an expert on cadmium plating processes but I do know the nylon remains in place. I pay professionals to play with the chemicals for this stuff...
Dave, You electroplate with the nylon inserts in place. The plating chemicals do not attack plastic or rubber. In some cases the surface of the nylon insert is discoloured depending on the chemicals used. This is easily rectified by lightly scraping the nylon with a knife blade. FYI Dinos (other than the 206 and 246L) have little to virtually no cadmium plating. Correct is zinc, either clear (aka silver) zinc as is the case with these nuts, or yellow (aka gold) zinc as you find on the brake calipers for example. I mention this because I have heard the terms zinc and cadmium plating used interchangeably and they are not the same process. Best Regards. Paul
With exception of "yellow" insert, most "reproduction" yellow or other readily available insert color nylocks seem to have numerous incorrect appearance details, including plating when compared to OEM items, but more importantly, most seem to be lesser grade (hardness/tensile strength) than OEM ones, which are/were 10.9 or 12.9 while most todays "aftermarket" examples appear to be 8.8 or less. It might be a good idea to take this into consideration when choosing hardware for steering, suspension and other critical applications.
The grade is stamped on the fastener or indicated by hash marks on the top (where the nylon insert is crimped in my the rolled over metal)
Thank you. Having been involved with vintage car restoration for nearly 40 years of which over 25 professionally, I'm somewhat familiar with hardware grade identification. My comment was offered merely as a caution for those who may not be. And if in doubt, Rockwell testing can become useful.
Absolutely. I took your comment very constructive BTW, just adding to it And, I don't know when fastener grade identification started.
https://www.metricmcc.com/ I have, over the years, found these guys to be very useful and helpful in my semi-continuous quest for metric fittings. They do have M8 x 1 I don't know if they're high enough for this application, but they have never failed to have what we needed for German presses, Italian gluers or Swiss die cutting machines. D
Thanks Dave, they only have the shorter DIN 985 in 1mm pitch. I didn't contact these folks but I did talk to victory and mdmetric after checking a dozen other places online, any of these should find it if available in the world. Tough part is getting their attention for small quantities, I'll keep them in mind for next time. At any rate, Rob was kind enough to solve my issue! There is another unusual size nylock for the starter motor mounting, M10x1.0 which is an "extra-fine" and only earlier cars had it, they went to M10x1.25 on E-series. This one is available from mcmaster fortunately...
