Enclosed tool better right! Absolutely wrong size in the garbage and brings tremendous Verletzungsgefahr.Steckschlüssel is torn when slight wear and has torn my finger ... nasty wound äust only unpleasant. Fasteners partly with extremely unclean cut threads. After mounting bolts are still some out better with caps on in order to minimize further injury. Wooden stairs were so far relatively OK but out on the surface. It takes 2 siebzehner nuts and 2 guns as an alternative tool, normal keys do not work because screws are partially submerged.
