Which Riv Nut tool

Recommended Posts

Yorkshire_Pudding

Hi guys,

 

has anyone got any recommendations for a Riv nut gun? Not wanting a cheap and nasty one but not a mega £££ neither. 
 

thanks

Andy

The Memfast one, where you wind the Rivnut up until its fully expanded and seated, worked well for me during my build 10 years ago.

For the small quantity needed, compressing with long bolt, nut and washer is all I've found necessary but I hate spending money on tools that will just gather dust😨

I’ve got the Memfast too, really good with all types of Rivnut, have used it with M8’s with no issue, though mainly M6, M5 etc.

I use a short arm Sealey AK3984.  Works well if you have straight acces.

I’ve got an RS one, can check later which one if needed. It must be OK, I counted the rivnuts in the project chassis yesterday.....551 M4 plus a thankfully much smaller number of M6

 

Plus all the ones in the panels I’ve not counted yet.....

 

Good grief.

I had an RS one, not great I found, (and others that borrowed it), tends to go through finer size mandrels, which were a specialist part, when replacements are needed.

 

The Memfast is very good, it doesn’t seem to go through them as fast - I think lacking the scissor action means less bending strain on them, but, cunningly, they’ve found a way to use big standard Allan bolts as the mandrel, so they’re dead easy to replace.

I dunno, blame the tools....  :)    I can certainly see how the lever style devices could break smaller mandrels as it takes a certain technique to avoid off-axis load when setting the rivnut.  I have an old Memfast kit for M5 that I bought years ago for a specific job, and another brand of similar type for M10.

Another vote for the memfast one. Had several over the years but this one has stood the test of time being used on three builds where I use a lot of fasteners so that the car can be easily disassembled rather than drilling out rivets.

 Can easily get into tight spaces as well.
