They work great. Just remember to torque them down fully the first time, they can strip out in the hole if you don't.
Great for holding access covers, mirrors, door handles, and other low load stuff like line clamps. I wouldn't use it to hold chassis components, muffler hangers or a body.
We use them routinely for the tool mount brackets in our Fire Apparatus fleet. Have done so for 20+ years with great success. Normbc9
Saw them used by Brookville in one of their frames as body mounting points. Just sayin' I'd like to do the same but am a bit skeptical.....
They are awesome, I use them almost everywhere. Use the steel ones you will never have issues with them. There are heavy duty versions available that spread out differently on the back side and hold a lot of weight or torque.
Those are weld in bungs, nowhere near the same thing. They have their place, the nutserts advantage is they go in with no welding like a pop rivet. I have two tools, the hand one does from 8-32 machine screws up to 1/4". A long handled version does the larger 5/16" and 3/8" inserts.
I hate the bastards, may be great in Cali, but in Wisconsin a little rust in the threads and they spin in the holes and you are screwed trying to get bolts out. The only place/time I use them is where/when I'll never have to disassemble them again! If you need bigger stronger threads in thin stuff, weld on an overlay or drill a bigger hole and weld in a bung and tap it.
Yeah, there's nothing more frustrating as one of these things spinning in the hole. I've used them, but only the steel versions and I'll put a couple of tack welds on them, as well as using antiseize...
Dissimiliar metals (different fastener vs nutsert material) can also be problematic as they can/will develop corosion. A little dab of anti-seize is your friend.
if you can find the steel ones and installed right they are quite strong we used them on trucks all the time as your not allowed to weld to the frame and in some spots you cannot access the back side of part to be bolted . the ones I use are a cone style not aluminum pop rivet style you have to use a impact gun or the special press to pull them like a huck bolt in place . the aluminum ones are garbage . and you should use anti seize on the threads of the bolts when using them so you can get it apart later on .
Use the RIGHT size drill and the proper insertion tool.I personally don't liker using larger than 1/4" bolt size.
I've used them with all the above results. I drill a hole slightly smaller, file to "just" fit the nutsert and crank them down good with the installation tool. Better choice for any load is a caged nut
good for light use only, i've bent the instalation tool putting them in to.(american made) i love the idea of them, being able to put threads from one side only, but for me they have not lived up to their reputation yet. to the guy building airplanes with them... i dont know about if thats a good idea. may on some drink holders or a map holder.
There are many different varieties of "nutserts". I use a lot of the 10-24 and 1/4-20 sizes. Do your research, as some styles are crap. I only use the cad plated steel, ribbed style. I get mine from McMaster Carr. Do NOT use those that break in the middle and pull the threaded portion up into the barrel. I have used those in the past, and had them work loose. I have had excellent results from the style I now use. Anything larger than 1/4", I would recommend welding in a threaded bung.
I worked on aircraft for 35 years ,28 with the airlines, they are used quite a bit, Only they are called RIVNUTS and are made different than nutserts.If you have ever flown on a airline, You have parked your Butt over hundreds of them.
if he had asked about "rivnuts"i would have had no comment to make, but he was wanting to know about "nutserts". you should show a pictures of the ones you're talking about, I know I would like to know more about them. or do a torque test with them to show what they can do before they fail. anybody set up to do a test on both? i'm on the edge of my chair just thinking about it!
To fit panel steel parts to panel steel they are the ducks nuts . But for structural stuff even with the large flange nutsert jobs I would have my doubts. We recently fitted a deck lid to a project and it was probably more than they were intended for and two nutserts spun in the thin panel steel and OH MY what a bitch to remove. But I would sur still use them in low stress applications every time.
^^^^^^^^^^^^^^^^^what he said, used them for years, great for cable and brake line installs, small componants. fine for shear type forces not so much for pulling forces. Probably wouldn't use anything bigger than 1/4 / 6mm. Steel inserts, steel bolts, antisieze. Nothing like repetition
