Thread: Rivnuts?

I saw these on epay and was wondering if they are any good or just a gimmick?
I would be hand where you cant get to the other side.

Use them all the time (may be not that particular make but something very similar), mainly for sheet metal work. Work well!!

I use them often. Have that type of tool as well as a couple of others. One is used with a cordless drill. The other is one of these -

This is a heavy duty tool for larger Nutserts, especially stainless.

They are really good, we use them at work a fair bit.

I've used these a fair bit in sheet metal work and I find then very useful. I don't have the tool myself but borrow the Nutsert kit fron work.

Perhaps the best application was in the cargo area of my van where several dozen 6mm diam Nutserts along the inside of the body act as anchor points for 2.4m long SHS AL tubes that run along the top/middle of the sides of the van. The tubes act as rail like anchor points for tying down stuff much like the rails that run along the sides of truck beds and are used to anchor loads.

This was my old van which only had the rails running down the middle of each side the replacement van has then up bear the roof as well.
If you have enough of then then can take a fair load.
The floor of the van has 6 folding eye bolts that also act as anchors.

I did this 3 times over a 4 year period. The first was in 2007 to our old 1980 Mitzi van. Then a year later I traded up to a 2004 HIAce and new rails when into that one. When that van was totalled in a minor bingle in 2010 I rescued the rails before they towed it away and put them into a 2008 HiAce - so I ended up going through a heap of Nutserts.

I used to use a very similar looking Radio Spares set a lot about 25-30yrs ago. That was a set made in England and sold here by the England based Radio Spares company. The RS unit was very good, the actual plier set was no hassle but a couple of the mandrels did fail after inserting maybe 800-1000 inserts, they slowly developed a bend and ultimately failed. So if you buy a set, either make sure you can get replacement mandrels, or be prepared to either not be able to use a size (it will be the one you have used the most), or prepared to replace the complete kit every so often.

The system works akin to a pop rivet puller, except that instead of the rivet having a breakable shank to set it, this system used interchangeable mandrels mounted in the pliers, and the nut is screwed onto the mandrel, located in position, pulled to lock it in place, and then the mandrel is unscrewed from the fixed nut, leaving a clean thread in the nut ready to take a screw at a later time.

We found the system great for sheetmetal and for thin wall tubing, but it does need accurately sized holes, often with diameters slightly of regular 0.5mm rise drill sets, e.g. from memory the drill size for 3mm inserts with the unit we had was 5.8mm or thereabouts, 5.5mm was to small to accept the insert and 6.0mm was to large for it to grip properly in the metal.

Never seen these before but definitely will be getting some, I can unlimited use for them in my shed.

Car manufacturers (Holden) use them also, not in a round hole but hexagonal. I've a set also, wouldn't be without a set. As someone mentioned the threaded section has a tendency to let go, usually on a weekend, when supply shops are closed. DAMHIKT. Get a few HT bolts to match the threads, as sometimes you can't get the tool in the right place, and use the bolt to pull up the nutsert.

Seems very cheap to me I would not expect too much from it

A couple of months ago I took our CFA truck for its weekly test run. When climbing into the cab the top grip handle in the middle of the front pillar pulled off in my hand. Luckily I did not fall. Now I know how it was attached. The handle mounted on the surface facing into the cab and extended towards the rear of the cab maybe 100mm. This meant there was a lot of leverage acting against the mount point.

I took the truck for a run again Friday and noticed a log book entry saying that the handle had been taken back to the workshop for modification. It would be interesting to know how they will fix it. Bigger size maybe?

Nutserts are very versatile. Avdell is one of the leading brands of hand guns and pneumatic guns; substantially more expensive than the epay item.


Thin Sheet Nutsert® - Avdel Global :

The riveting gun shown in the link in the original post looks like it has been adapted from a cheap conventional riveting gun. I have used one of these and they struggle to set M6 or greater rivets, especially in SS or Steel, and the same will apply (perhaps even more so) to Nuserts.

Another thing is that unless you have Popeye forearms (i.e. strong hands) you won't be able to do set many of the larger size Rivnuts consecutively. The one I borrow from work looks more like the HD one SurfinNev shows a link to, and has a ratcheting action that uses two arms/shoulders which makes it much easier to set the bigger Nutserts/Rivnuts.

If you need to set sizes larger than M4 but don't want to pay top $ then a two handed kit like this one is probably a reasonable half-way house

I was looking at this unit yesterday and it looked sturdy and well made enough and it has M3 to M10 capability.
Probably available at half that price on eBay.
