Anyone know what these are called, and who makes them?

Anyone know what these are called, and who makes them?

(OP)
I'm trying to find these rivets for fixing plastic assemblies together. They have a fast thread on them, and they are simply pushed (with force) into place, in a blind hole, for instance.
What I've modeled quickly in CAD is a representation of how I remember them looking.
Any ideas as to what they are called, or who makes them? I've done a ton of Google searching and just can't find them.
Thanks in advance,
Mike

RE: Anyone know what these are called, and who makes them?

That type of fastener will not work very well in plastics unless you only need a little grip. Even in metal they are only for light fastening, like name plates.

Thanks guys,

mcgyvr, they're not quite what I'm after, but thanks for bringing them to my attention.

TVP, the SPIROL® Twist-Lok™ Series HP300 Pin:

is most like what I had in mind, though their standard ones are tiny - looks like they make specials, though.

btrueblood, the U type drive screws are pretty close, but I was after something with an un-fluted shoulder section. Thanks for showing me those, though, I think I can use those elsewhere.

Cheers,
Mike

Compositepro, you may be right. The application is to attach some wheels onto a plastic injection-moulded toy car - hence my need for a section of unfluted shoulder, to act as a bearing/running surface for the wheel.
It would be nice if I could find some, off-the-shelf, that were the right kind of size, but if I get hold of some samples of Spirol's bigger Helical Knurled Drive Studs, I can try them out.

RE: Anyone know what these are called, and who makes them?

I associate the fast helix with 'drive screws', and with Parker-Kalon, now part of Emhart.  It appears that P-K no longer makes them; they were de rigeur for attaching metal labels for decades.

I've never seen one with a plain shank as you have depicted, or over an inch long, so maybe we are thinking of different things.

As it seems impossible (I have also tried) to find your exact ready produced product, you will probably have two ways left:

Either ask a special manufacturor to produce after your needs, or to redesign your product to already existing fasteners/bolts.

Could below be a place to start? (Should be a number of possible producers and materials around)
