This 70-piece screwdriver set in a blow-moulded case (BMC) is a comprehensive manual screwdriver and bit assortment intended for workshop maintenance, site engineers and general assembly tasks where a wide range of tip profiles and sizes is required. The set provides interchangeability between fixed-handled screwdrivers, precision drivers and a selection of bits and holders so you can tackle slotted, Phillips, Pozidriv and Torx fixings with one portable kit.

The shafts and bit blanks are manufactured from chrome vanadium (Cr-V) and S2 tool steel respectively, with tips hardened and tempered to resist rounding and cam‑out during repeated use. Shafts are finished with a satin/chrome plating to improve corrosion resistance, while the driver tips are black-oxide treated to aid screw grip. Handles are bi‑material, ergonomically profiled for torque transfer and reduced hand fatigue; the main drivers have a recessed cap for controlled thumb pressure and accurate manual turning. Tip profiles and dimensions are produced to industry standard tolerances (DIN/ISO/BS) for consistent fit with corresponding screw heads.

Typical applications include mechanical assembly, maintenance and repair, electrical and telecommunications installation (where insulated manual control is required), automotive trim and panel work, and light engineering. The mix of full‑size and precision drivers makes the set suitable for bench technicians, service engineers and advanced DIY users who need both coarse and fine control over fasteners in a single kit.

Key benefits of the set are durable tip strength and compatibility across multiple screw standards, reduced corrosion thanks to plated and treated surfaces, and the convenience of a rigid BMC case which protects and organises 70 components for on‑site transport. The hardened tips minimise wear and help preserve screw head integrity across repeated cycles.
