Abstract: A self-drilling expansion fastener is integrally formed of a sheet metal material for locking two or more sheet workpieces together, and includes an expansion structure and a drill structure. The expansion structure has a plurality of internal threads and force-distributing bars. The drill structure has a chip guard for covering a head of the expansion structure, and a drill forward projected from the chip guar for self-drilling a hole. When an externally threaded element is screwed into the expansion structure to mesh with the internal threads, the force-distributing bars are brought to expand outward and are finally compressed into a folded state to thereby tightly lock the sheet workpieces to one another. A method of forming the self-drilling expansion fastener is also disclosed.

Abstract: 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 screwed 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.
