Dealmonger: Rivet Nut Tool Kit $18

DM Seeleys is selling this no-name-brand rivet nut tool with a kit of common rivet nuts for $18. Rivet nuts work great if you need a blind fastener but, due to material thinness, you can’t put a tapped hole. Insertion of a rivet nut is pretty similar to using pop rivets, but you have to unthread the mandrel after applying the nut.

While I have a cheap rivet-nut tool from another vendor, D M Seeleys also carries 100 packs of inserts (2 sizes at 50 pieces each). It’s hard to find inserts in smaller quantities, so it’s nice to find this site offers some “refills”.
Looks like it’s gone now.
