The Vevor adjustable torque screwdriver is designed for precise fastening in electrical work, light industry, machinery manufacturing, and research applications. It features a 10-70 in-lb torque range with 1 in-lb increments and ±5% accuracy for controlled performance. Built from chrome-vanadium steel, aluminum alloy, and rubber, it offers durability and a comfortable grip. The screwdriver clicks when the preset torque is reached to help prevent over-tightening. A carry case and multiple bits are included for convenient transport and versatile use.
