The GREATMAX 136423 3/8" 120-Tooth Flex Head Digital Torque Wrench is designed for controlled fastening in professional automotive repair, motorcycle servicing, mechanical assembly and workshop maintenance.
Its wide 2–135 Nm torque range provides the versatility required for both lower-torque precision fastening and demanding automotive applications. The digital measuring system offers an accuracy of ±2%, supporting consistent and reliable tightening.
The 120-tooth fine ratchet mechanism requires only a 3° swing arc, making the wrench particularly suitable for fasteners located in confined working areas. Its flexible ratchet head further improves accessibility around nearby components and obstructions.
A large color LCD screen provides clear torque readings and improves visibility during operation. With an overall length of 420 mm, the wrench offers a practical balance of control, leverage and accessibility.
The wrench is supplied in a durable blow-molded case with a color sleeve. OEM branding, product colors, manuals and packaging can be customized for professional tool brands, importers and distributors.

Does the 120-tooth ratchet make the torque wrench more accurate?
No. The 120-tooth mechanism provides a small 3° swing arc for improved access in confined spaces. The ±2% specified torque accuracy is determined by the measuring and calibration system, not by the ratchet tooth count. Learn more about what a 120-tooth ratchet means on a digital torque wrench.
