Goyojo GM340 Digital Torque Wrench is a high-precision, professional-grade fastening tool designed for automotive repair, bicycle maintenance, and industrial engineering. Engineered for accuracy and durability, the GM340 replaces traditional click-style wrenches with a digital interface that provides real-time torque monitoring, ensuring you never under-tighten or snap a bolt again.
Ultra-Precision Performance: Delivers professional-grade accuracy of 2.5% clockwise and 2.5% counter-clockwise, ensuring compliance with strict mechanical standards for engine builds and aerospace applications.
Dual Mode Functionality
Peak Mode: Records the maximum torque reached—ideal for verifying tight tolerances.
Track Mode: Displays real-time torque pressure as it is applied, preventing over-torquing before you reach the target.
Tri-Alert Notification System: When the target torque is reached, the wrench provides instant feedback via a High-Decibel Buzzer, LED Visual Flash, and Handle Vibration, making it easy to use in noisy workshop environments.
Four Unit Conversions: Effortlessly switch between four common units: NM, in.lb, ft.lb, and kg.cm, eliminating the need for manual math or conversion charts.
