HARDELL Rivet Tool Kits, Rivet Nut Pliers Set, 14" Heavy Duty Hand Rivnut Gun with 150 Rivet Nuts and M3 M4 M5 M6 M8 M10 6 Metric Mandrels，Heat-treated Alloy Steel better for Thick Sheet Steel

The Rivnut tool is good and the mandrel looks strong.I am not using the larger mandrels but best so go carefully and make sure you are not twisting the angles of the gun.Worked great for me.

Brilliant tool - Great quality ..

So much better than the diy bolt method......granted with this you do need the space in order to use it. Very easy to use, plenty vids online. I use mostly aluminium M6 riv nuts ( you can get open and closed riv nuts ) and this makes it a breeze....so quick. The one thing i did ( i do it to all tools ) very lightly grease threaded parts....and dry teflon coat hinge sections....

I used this nut-rivot tool to replace pop rivets on my cars door panel. It did this job brilliantly. However, I have reduced the product by one star as I feel it could be stronger. It's OK for diy jobs but not for prolonged use by professionals.

Worked perfectly to secure my TV bracket to the door pillar in my van. Just the job. Only minor negative is that although some of the nutserts provided fit in the case with the tool there is not enough room for all of them so they need to be stored separately.

Broke on 4th time of use (only 2 days out of return window!). The head which holds the bits has seized and can’t even open it with grips. Looked great but turns out to be poorly manufactured.

Worked perfectly .Well made and good value

Decent build quality in a nice plastic moulded case with accessories haven't had a chance to use yet
