The Vevor torque screwdriver is designed for precise fastening with a 10-70 in-lbs torque range and 1 in-lb increments. Its laser-engraved scale helps make adjustments easy to read, while the aluminum alloy body keeps the tool lightweight and durable. An audible click and automatic slip function alert you when preset torque is reached to help prevent overtightening. This set includes multiple bits, an extension bar, a T-handle, and a portable storage case for versatile everyday use.
