Buy DongCheng T40 x 100mm Heavy-Duty Torx Screwdriver Online at Best Price in India

The DongCheng HD090507 T40 x 100mm Torx Screwdriver is the largest and most robust model in the torx range, engineered for extreme-torque applications across automotive suspension, commercial trucking, structural steel framing, and heavy plant equipment. Built with an extra-thick 8.0mm diameter round shank forged from industrial-grade Chrome Vanadium (CR-V) alloy steel, it delivers maximum torsional strength and eliminates flexing under massive turning force.

Its precision-machined T40 star tip seats deeply into heavy star-drive fasteners, providing maximum torque transfer without slippage or head damage. Integrated with strong magnetic retention, the tip holds large fasteners securely in place during vertical or awkward assembly tasks. The ergonomic dual-color soft-grip handle provides non-slip hand comfort and maximum turning leverage. Packaged with an individual plastic hanger for pegboards.
