MM GVI Diesel Cylinder Head Nuts

Jeremy L · Aug 31, 2015

Would anyone be able to tell me what grade the 9/16" head stud nuts are on a 1961 MM GVI Diesel engine (the fine threaded ones)? We have a bad nut that the threads are pulled out on and we want to be sure we use the proper grade of nut as a replacement.

Regards,

Jeremy

Probably grade 5, the studs are just are not anything special. Grade 8 would also work.
