25Pcs Steel Multi Grip Rivet Nuts Pre Bulbed Shank Zinc-Plated Flat Head Threaded Insert Nut Construction Fasteners for Industrial (1/4-20)

Excellent quality

I use these to repair plastic tables that have wood screws holding the legs on drilled out the plastic and installed then used machine screws to finish the job works grate

I didn't think about needing a longer mandrel to use these but went with the manual method and it worked good. Exactly what we needed

3 out of 6 crush nuts failed from too much bolt to nut pressure. The Home Depo 1/4in x20 bolts snapped off because the nuts would not expand just twisted.. Applied lithium grease to threads then it worked much better without further failures.

I have a use for these that will allow them to be used both ways. I'll anchor something to a door and use either a sexbolt or these with a hurricane or sidewalk bolts. It works great and I don't need to worry about it z falling out.I like using these for so many different things.

Good quality worked as it should.

No problems

These crimp in easy as work as design. Not much to really say
