It's well documented that seasoned technicians have a hard time achieving proper specifications without a torque wrench. Topeak's 38in drive D Torq Wrench DX measures Nm, inlb, ftlb, or kgcm, ensuring even the greenest mechanic will achieve manufacturers' desired settings with ease. The D Torq has a range of 4 to 80 Nm and uses an intuitive digital display with audible warning that is programmable to your set values. The liquid crystal display is easy to read and Topeak includes two batteries that will last for 48 hours of use. The D Torq DX features a reversible ratcheting head with a standard 38in square drive. Topeak includes a hard shell case to protect the D Torq, and it includes 8 15mm sockets, T25, T30, and T40 Torx, along with 3 through 10mm Allen bits. The D Torq Wrench DX is 13in long, and the LCD has an auto off feature to preserve battery life.
