VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1929-1932 Aphrodite Bolt

My 31 Four Door uses Aphrodite bolts to hold the front bumper on. I'd like to use new ones. Anyone know a source? Thanks, Al W.

Can you be more specific as to what you are calling an "Aphrodite" bolt?

If you are looking for the bumper bolts for the front bumper face bar the Filling Station has them. Check out your Filling Station catalog.

Hey Dog that was quick! The fastener in question is a 9/16 stud having course threads, (12), on one end and fine threads, (18), on the opposite. I believe the FS has Bolts for this purpose and I'm being stubborn for no reason at all. Thanks as always, Al W.

Yep, they do. It is always a good idea to check out your Filling Station catalog first to see if they have the part or parts in question before posting an "Parts Wanted" ad.

Good luck!

JD, I'm sorry, I should have said that FS has standard Hex Head bolts. Aphrodite in terms of a fastening device is new to me. A mechanical engineer friend of mine stopped by last weekend and gave me the Term "Aphrodite". Al W.

My 31 had the standard bolts in it and other 31's I parted out over the years all had just the standard bolts in them. Chuck

I looked up the term "Aphrodite Bolt" on the Internet and according to the Internet there is no such thing. Be that as it may, if you are talking about the bolts that hold the bumper bracket to the frame they are hex head bolts. Check out your 1929-32 Chevrolet parts book since all of the bumper bolts and their sizes are listed in that book.

Some folks in the oil patch called crossover studs (with one thread on one end and a different thread on the other end) "Morphadite" , like a person with both male and female organs on their body, you know!

Ahhhhhh! Now I get it! Here's the mystery! My 31 came to me with "Morphodite" studs as the front bumper mounting fasteners. 9/16 Diameter stud having 12 and 18 threads. Is this odd? Thanks for sticking with me on this important topic! Al W.

I think the term is hermaphrodite-A person or animal with both male and female sex organs or a plant with both stamins and pistils in the same flower. Not sure how that relates to a stud with different thread sizes.

I have also seen them used in a cast iron head (course threads), with fine threads for the nut. There are several applications for them.




Karl,....You are right in what you say, but I was using the word as I have heard it used. Two threads on the same stud, get it?

Heck, I have always called those things plain old "studs". And no, they were not used on the front bumper.

According to the Feb 1932 parts book the bumper mounting bolts are 9/16-12x1-1/4" cadmium plate bolts w/lock washers. The bolts for the fender guards if using that style also uses 3/8-24x1" cadmium bolt, plain washer & a lock washer....Joe

When the Dog Barks wise men listen! I'm resting my case and buying the bolts from FS. These old cars can be very confusing! (And I'm a guy from the Ego driven world of Mid Year corvettes saying that!) LOL Thanks, Al W.

Don't know if the bolts supplied by FS have the larger heads like the originals or are just modern replacements. Both will work but moderns don't look the same.

I've found some of the bolts Chipper has spoke of at tractor repair shops. The bolts are about 1/3 thicker on the head...Joe

Yeah, but this has two male ends with different threads. One definition of hermaphrodite is "a person or thing in which two opposite qualities are combined". If you consider fine and course as two opposite qualities, the term fits.

Still not sure how or why it would be used on a bumper, though. They are probably just something someone had laying around that fit.

YEP, that is what it means! You ought to hear what they call a spsde!
