The Siegen 100 Piece Screwdriver and Security Bit Set is a comprehensive bit collection designed for tradespeople and technicians who work with standard and security fasteners. This extensive set covers virtually every common driver profile, making it ideal for maintenance work, appliance repair, electronics assembly and security installations where tamperproof fixings are encountered. Manufactured from Chrome Vanadium steel, each bit provides the strength and wear resistance required for regular professional use. The set includes standard profiles such as slotted, Phillips, Pozi, Torx and hex bits in both metric and imperial sizes, alongside specialist security variants of Torx and hex profiles that feature central pin compatibility. The collection extends to less common but essential profiles including butterfly, spanner, spline, square, Torq and tri-wing bits, ensuring you're equipped for specialist applications without needing to source individual bits. A magnetic extension bar, bit holder and 1/4" square drive adaptors add versatility, allowing these bits to be used with socket sets and power tools.
