The siegen 12 piece hammer through screwdriver set is a professional grade toolkit designed for demanding workshop and site applications. This comprehensive set features chrome vanadium steel shafts that are fully hardened, tempered and chrome plated for exceptional durability and corrosion resistance. The hammer through design allows the screwdrivers to withstand striking with a hammer, making them ideal for tasks where screws are seized, painted over or require additional force to drive home. Each shaft is shot blasted for improved surface quality, whilst magnetised tips help retain screws during installation, particularly useful when working in awkward positions or overhead applications. The set provides comprehensive coverage for both slotted and phillips head fasteners, making it suitable for electricians, joiners, mechanics and general maintenance work. Classic high impact resistant handles offer durability in professional environments where tools face regular use and the occasional drop. With sizes ranging from precision work to heavy duty applications, this 12 piece collection covers the most commonly encountered screw types across electrical, joinery and mechanical trades. The lifetime guarantee provides additional reassurance for professional users requiring reliable tools for daily use.
