Nie, dziękuję Przekieruj mnie tamTL;DR: 41 % of stripped screws come from using the wrong tip size [FastenerTech, 2022]; “cheap and good do not coexist” [Elektroda, Błażej, post #11219501] Add ~PLN 50 to the PLN 70 cap for chrome-vanadium drivers hardened to 54-58 HRC and at least one impact tool. Why it matters: The right steel, tip shape and leverage stop breakage and save seized fasteners.
• Chrome-vanadium blades: typical hardness 54-58 HRC, resist 160 N·m torsion [Wera Catalog]. • VDE-rated insulated drivers are tested to 10 kV for 1 kV use [IEC 60900 Standard]. • Entry hobby sets cost PLN 40-70 for 6-8 pieces [Elektroda, Anonymous, post #11198708] • Mid-tier pro sets (Wera, Bahco) start at PLN 120-180 for 6 pieces [Allegro Price Track, 2024]. • Impact driver can deliver up to 8× manual torque in one hit [ToolReview, 2023].
