iExcell 50 Pcs 1/4-20UNC Stainless Steel 304 Rivet Nuts Threaded Insert Nuts Nutserts, Flat Head

On thicker material instead of expanding it bends and jams the bolts. When bended Extraction is very difficult.Maybe rivet nuts should expand easier instead of being so rigid in the expanding area.

Great product and great price I use this for stainless steel doors applying hardware to them such as crash bars, doorhandles

Solid rivnut at great value

Tal como se esperaban. Vienen en una caja plástica bien organizadas.

Worked great
