Rivets..

OK, there are pop rivets and then there are the rivets that are swedged on one end. You see these rivets used in various applications, like holding the brush assembly in the starter.

Any idea for a source?

Oh, and what is the correct term for this type of rivet if not rivet?
 
Thanks. I can't wait to see what they say when I ask for four. I figure it will cost $1 for them and $25 shipping and handling, that is if they stop laughing. Oh, they are called semi tubular rivets. I may just take a trip to the local airport, there are two or three aircraft repair companies.

Darn I miss those military surplus places that were in business in Long Beach in the 70's. But then again, I no longer live in Southern California.
 
FOUR?!!?

Laughing, indeed. :laugh:
 
Ray, you could just make them from a nail or screw that is close.
If you know a local machine shop.
Hobby shop is a good source for small screws also.

Guess I'm missing something ... why not use a Pop rivet?

I need to attach about 1/2 inch Bakelite brush plate to a starter end housing, so I need a rivet of about 3/4 inches. Pop rivets do not allow you to control how much hold down force is needed for them to attach. If I break the Bakelite, then I will be looking for another starter and $$$. The only reason I need to remove the plate is to replace the rusted brush springs. But before I proceed, I will have to source them or make something as has been suggested out of steel rod, or just use a screw and loctite and/or knurl the end.

If I buy a thousand, are any of you guys interested in some. :crazyeyes:
 
My local hardware store sells many different rivets in the parts boxes. ISTR even hollow aluminum ones that you can set wuth a tapered round rod.
 
Peter, thanks, and yes my ACE hardware has the rivets, but not long enough, they have grad 8 and grade 5 NF bolts as well, but not in the lengths I need, like a grade 5 3/8 x 7/8 NF no where to be found, they jump from 1/2 to 1 inch. It drives me crazy.
 
Ray, no local hardware store stocks grade 5, fine thread bolts, in 1/8" length increments and sells them one part at a time!
That's why hacksaw's and grinder's were invented.

Sure they do, at least as much as ordinary rivets do. You don't _have_ to pull until the stem breaks. For that matter you don't even have to use the stem to set them, if you don't want to. Just drive it out the other way, and what you have left is a hollow rivet.
 
Randall, yes I have done that, but it is not a hollow rivet that I am seeking, it was a semi-tubular rivet. I have one more source to check out, an auto electrical repair shop across town. I need to go there anyway to get the armature dressed. If the shop does not have the rivet, I'll just get some aluminum or mild steel rod and make one.

As to grinders and hacksaws, been there, done that. I have enough odd bolts to replace and the other readily available ones, I will just put a big order together and be done with it...

Thanks all for the help.
 
You ~DO~ know better than to use aluminum in this application, too!

...what better place for electrolysis and high temps than RIGHT where the current is most drastic? :devilgrin: :smirk:
 
7/8" is not as common a size capscrew as you might think. 5/8" is common. You will probably best off to grind 1/8" off a 1".
 
I apoligize for highjacking this thread, but:

In a related question regarding fasteners, I often wondered how the thread pitch is determed for an application. What I mean , say you need a 1/4-inch fastener. What factors determine whether to use 1/4-20 or 1/4-28? Is there an advantage or disadvantage in using fine vs coarse threads? I have noticed very few coarse threads in my TR's!
 
As I understand the design, if you compare a fine thread bolt to a course thread, the fine thread bold has about 9% more stress area in the threads. This means the fine thread bolt can take more torque to tighten, which means fine threaded bolts are less likely to come loose because they can be preloaded more the course.
