Rivnuts and Nutserts

Can someone give a brief description of the differences of the two? When
one would be used instead of the other?

Rivnuts when installed correctly, will draw up and expand only on the
portion protruding thru the opposite side of the material. Works great for
installation into most hard or rigid materials and like rivets, come in
varying lengths to accomodate material thickness. Anti rotation device is a
provided by a notch in the hole that "keys" the fastener.

Nutserts (not nut plates) are not as commmonly used on the other hand expand
along the entirel ength of the sert, and is more conducive to aplications in
soft materials such as honeycomb, fiberboard, etc. I have seen them simply
epoxy potted in place on honeycomb and other laminated material. Anti
rotation device is provided by a serrations around the circumference edge
which makes hole size and depth critical

I dont believe EITHER of these is considered to be a structural fastener and
both are problematic when they become loose.

Hope this helps

Hi All,

I've tried using rivnuts, but have ruined the threads on the tool piece
each time. How does one know when enough force is used and not too much?

depends on the puller - if you use the small one shaped like a top that uses
the Allen key, you get a feel for it when the allen gets a smidgen harder to
turn. The more righteous pullers are the long ones with the pull handle
that quick threads the rivnut onto the tool before insertion. Those have an
adjustable tip so you can pretty much calibrate the amount of pull on the
rivnut. They are quite a bit faster too especilly if you have several to
pull

I think US Tool sells both types of pullers

Mike, the driver that I've used is very similar to the Pop rivet type that
is squeezed like a pair of pliers. I tend to squeeze as I would to set a Pop
rivet, but with dire results. Is this the same type of tool that you refer
to as a "righteous puller"? It would seem that there needs to be some sort
of torque setting control, as there isn't much feel for when the nut is set.

what you are describing is the 'preferred' puller. First make sure you are
using the correct length rivnut for the thickness material. Second, adjust
the tip on the end by scewing it in or out. Doing this will adjust the total
travel of the anvil, and this the total expansion of the rivnut. This is a
nice feature on this tool because, once set, it pulls a perfect rivnut every
time.

Screwing the tip out increases the throw, screwing it in decreases the
throw. If you are stripping riv nusts, you need to screw it in.
If possible, get a test piece the same thickness as your work and calibrate
the tool before you do the installation
