• Rivet nuts are made from aluminum alloy which provides strength, corrosion protection and long service life
  • With open end, small flange, round hole, threaded inner wall and partial anti-skid surface, these flat head rivet nut has a good performance of fastener function
  • There are various sizes, M3, M4, M5, M6, M8 and they normally have low profile compared to other nuts
  • Each size includes many pieces of rivet nuts so you don't have to go to hardware store searching rivet nuts for a while
  • Comes with a rivet gun and many mandrels and nosepieces for convenient riveting

this is exactly what i needed and works very good for what i need.

I used this to install M4 steel riv nuts on my blasting cabinet and had no problems. I purchased a larger one for more money, but it didn't have the M4 mandrel so I bought this one. Not sure how it would work with the larger mandrels.

Great value, works great

It's great to have new threads , these do the job great , but take care they are made of aluminum.
