Should I have a stud and wingnut instead of a hex bolt holding down my battery ground strap?

MBMB,

I had a wingnut on my 81, and have a hex bolt on my 90.
So I assume that Porsche "upgraded" this item (or ran out
of wingnuts and hex bolts were cheaper) sometime in between .

It certainly makes life a lot easier each time you have to undo it. I wonder why the stud was removed...

the wingnut is what I would go with for ease of disconnecting the battery.

"Wingbolts" are in both cars, but a bolt is the equal, if not better ( easier to slide a wrench in there than a reverse wrist twist!): the only issue is a clean, tight connection.

Depending on the length of the bolt/wingnut, the bolt can actually be quicker to remove completely.

I have a bolt on my 90', but want to install a battery switch there. Unfortunately, no battery switch that I know of fits without modification.

I'm going to get a wingnut, the regular nut ... in a car fire (been there) ... is not conducive to a zero-panic situation.

Mine had a bolt, I installed a stud & wingnut for greater convenience.

The stock equipment for your car is a hex bolt. Stud and wing nut sounds like a good idea....remember that the hex bolt is metric, so you will need a metric stud and wing nut.

If there's an electrical short circuit and you need to get the battery cable off ASAP, a very hot wingnut isn't going to be much fun either. Don't ask me how I came to that conclusion.

A hex bolt is not stock, a wing nut w/stud is stock. I own 4 brand spanking new ones that came with a Porsche 928 XXX XXX XX part number and everything. Don't know if you can still get them though. No stud either.

J E I believe that would make you, " King of the wingnuts " ...............

DOH!!!!!!! Set myself up for that one.

Correct me if I am wrong though, are they still available? I seem to recall I got them from some place Porsche NA (that's North America not Not Available) directed me to when I couldn't find a replacement. That's why I got extras. I didn't even have the fleet then. So naturally, I had to get a 928 for every wingnut I owned.

I was specifically addressing MBMB, who has an 89 GT, the OE attachment for the ground strap in the rear bay is hex EDIT Bolt, not nut. Sorry If I did not make myself understood.

Porsche technical bulletin, replace the wing nut with a nut, no explanation as to why.
