I'm needing a few nutserts for a project I'm working on.  

It appears that 3/8" is the largest.  They offer a lot of kits with several sizes included.  It appears that my best route would be to purchase the tool and then packages of 1/4", 5/16", and 3/8".  I can't see me using any of the smaller sizes.

I need to attach some things to the firewall and can't easily access that area (too old and fat, also dizzy when upside down).

Any input?????

thx,

Buy a quality kit from one of the major tool supply houses. The HF nutsert tool is junk.

I use a ton of 10/32 inserts. 1/4 and 5/16  a lot. 3/8 every now and then. I had to get some 1" aluminum tubing to serve as tool handle extensions to be able  to set the 3/8 insert. I used the plated steel inserts. Generally the aluminum incerts aren't worth fooling with.

My kit was from AVK Industrial Products and was called the Prototype & Thread Repair Kit P/N AVK 2292 (Inch). I use it a lot.

Thanks Charlie,

That confirms one suspicion, that the aluminum ones are not what I want.  I guess two suspicions.  I figured the HF ones were low quality.

just a thought...

there are rivnuts

there are well nuts that are Rubber flanged devices that push through a hole and then items are fastened to the top and the shank of the well nut is pulled up to expand to prevent pulling out..  if you decide on a rubber well nut.. please pick up a deburing tool and debur both sides of the hole... so it does not tear up the well nut..

you can also install riv nuts without a tool.. just with a strap with a hole and a bolt through it that stops the rivnut from spinning then the bolt to pull up on the threaded section..

McMaster Carr is a good source for replacement inserts.

I have a kit at work that I bought from Napa, made by Marson I believe. I can get a part number tomorrow if your interested. It included a number of inserts in 10-32, 1/4, 5/16, and 3/8 and all the mandrels needed to put things together. They sell just packages of inserts of which I have had to reorder both 5/16 and 3/8 inserts.

I'm with Frank. I buy replacements From McMaster Carr and I have a Kar Products tool.

I have never liked nutserts or anything that is supposed to expand in a round hole. The buggers come loose and turn, and you will then have hell removing the bolt if the nut is inaccessible.

For thin panels I much prefer cage nuts that fit a rectangular hole, and apart from filing the rectangular hole, no other special tooling is required.

The ones I use are steel, and knurled on the outside, They don't turn if they fit the hole tight.

I have a Curtis tool, no longer made, priced out of the market by cheaper tools, but none of them as well made. Here are some other ones. I have some of the first two in different sizes, good in close quarters.

I bought the kit, a quality made in England tool that looks like a pop rivet tool.

I got all the sizes right from the small 8/32 machine screw size all the way up to 3/8".

Like you I thought I would not use it much.  Wrong !!

I love the darn thing. I found myself going all over my projects eliminating bolts with nuts and also any sheet metal or self tapping screws. Gone !

The 10/32 machine screw sized insert is one of my favorites and very useful as is the 1/4".

I use the inserts pictured above, the ones with the ribs aroung the outside, they don't slip and can take a reasonable amount of tightening.  

Don't know what I did without it.

I've had good results with the longer reach ribbed inserts in fiberglass. When I'm set to put the inserts in I mix up a small dollop of bonding agent and spread a little around the insert. They seem to hold very well.

There's a number of nutserts in my cpe and they've been there since 97 with no problems yet
Some days it\'s not worth chewing through the restraints.

I have the AVK set as well.  The secret is to get good at putting them in, it is not a givin thing that they'll stay unless you learn to install them proper.  
I prefer weldnuts and plan to get a broach for those cage nuts.
