Hilitchi 165pcs Mixed Zinc Plated Carbon Steel Rivet Nut Threaded Rivnut Insert Nutsert M3 / 4/5 / 6/8 / 10/12

Great set. Take your time and practice with a few as too much force warps them and makes them difficult to screw a bolt in. I'm using them as external items for my vehicle and so far have held up agaisnt rust. Great set for the value.

Haven't had a failure yet............nothing super structural but if the hole is properly sized then it is a matter of feel as to tightening them in place.I love riv nuts - once I was introduced I almost go looking for places to use them!

These rivnuts are in a plastic box labeled for their size. Makes it easy to select what I need. They work great, and once crimped, they hold very well.

I tried to use some to mount a tool box in my truck. I found they did not like to work with the spray in bed liner. In other applications in regular sheet steel they worked as intended.

Nice variety of nuts, this set prepares me for the inevitable ... proper dimensions per size, they fit the screwbolt properly and squished tightly .... good investment for the future with the Xth-Nth model BT619 hand nut riveter!See my review of the tool ...

I bought them the first time, and I will buy them again. Don't expect the durability of industrial grade stainless steel. They have set well and no sign of spinning.

I bought these to replace the ones that come with smittybuilt products for my Jeep and these work so much better. Worth the money just for peace of mind.

Works as intended. Good choice of typical metric sizes.

Exactly what I needed! These Rivserts are perfect for adding attachment points to any solid surface. You do need the purpose built tool. This is the Metric kit, so be sure this is what you need or purchase the matching bolts. Could have used more of the two largest sizes, there's only 5 each of those.

Wow. Worth the money. Good quality and metric exaclty what I needed to finish a project

A good mix for the price, but the largest of them won't fit my nutsert unit (too big). They hold just as well as other brands (so far)...

Good kit

Nice set didn't put them to use yet but will become indispensable to mount equipment on my 4X4 ! I should have got these a long time ago ! you can mount them without the specialize tool just with a racket and a key ! but it's so easy with the specialize tool ! these rivet make mounting hardware solidly so easy on any thin pieces of steel on every mechanical project .should be in every DIY arsenal kit !
