An expansion mounting sleeve includes a forward tapered cylindrical body formed by stamping a material strip, and the cylindrical body defines an internally threaded tapered bore. A plurality of engaging teeth having different heights and shapes are formed to project from the cylindrical body. After the sleeve has been driven into or mounted in a hole formed on a wall, a ready-made bolt having length, size, and screw threads matching the threaded bore of the cylindrical body may be crewed into the bore and thereby expands the tapered cylindrical body of the sleeve, causing the engaging teeth to move outward to tightly engage with the wall in the hole and firmly hold the expansion mounting sleeve in place in the hole. A method of forming the expansion mounting sleeve is also provided.
