[alfa] RE: "Captive nuts"

These are called rivenuts (pronounced as in river-nuts) short for rivet
nuts. We use them all the time e.g. just last weekend when a radiator
side-pod got ripped off and we put a new one on. They are great provided
you take car in installing them properly. Anyone who sells Dzus
fasteners will also have these and the special tool required to install
them. They come in a range of sizes with appropriate tool-attachments
for installation. If you don't have a source, Pegasus Racing Supplies
http://www.pegasusautoracing.com are sure to have some.

By the way - Alfa drivers rule! We got a 2nd after starting back of the
grid (qualifying problems), a dnf when a cv joint broke, then a 1st for
the last race after starting from #2. As well - fastest lap time in each
race, and yes we are still running an outdated (12 yr old) car... ;-) so
we've been told.

Don't believe this is the correct term. I'm referring to the round
(generally aluminum?) threaded tubes where one installs by drilling an
appropriate sized hole, inserting the tube, then screwing in special
tool (and size) then tightening which crushes  the the inner / outer
portion of the tube...not unlike a pop rivet.

What is the proper name for these tools and does anyone have a
particular brand they would recommend? I bought a Harbor Freight version

some years ago. The main tool itself is quite well made and sturdy.
Unfortunately that is not the case with the threaded parts which go with

each size of the "captive nuts". The threads on the end are bad and the
outer threaded "cap" broke in two.

Are these universal so I can get just the end parts? I also had problems

with getting the nuts to crush evenly and solidly. Later when threading
in the bolt, it was not unusual for the "captive nut" to turn.

I need to do 18 on the three '69 Spiders and don't want to turn it into
an all day job.
