Micro Torque Wrench (Lock-Up Setting Series) is a premium, high-precision industrial fastening instrument designed for automotive engine calibration, aerospace component installation, critical electronics assembly, and high-density industrial maintenance. Engineered to deliver precise tightening control, this micrometer-adjustable click torque wrench prevents over-tightening or uneven joint clamping pressure, which can lead to structural fastener failure. The standout feature of this series is its industrial lock-up setting ring, which prevents accidental torque changes during high-repetition assembly tasks.
Feature
Advanced Lock-Up Ring Integration & Micrometer Scale Precision
The physical mechanics of this tool line prioritize accuracy, user safety, and long-term calibration stability:
- Accidental Shift Prevention Lock-Up Handle: Equipped with a mechanical pull-down or push-to-lock collar ring at the base of the handle. Once the operator twists the handle to align the exact torque value on the high-contrast micrometer scale, the lock-up mechanism clicks firmly into place. This completely eliminates handle drift caused by hand friction or glove rubbing during high-leverage operations.
- Tactile and Audible Click Notification: Built with a heavy-duty internal spring-and-pivot block configuration. Upon reaching the pre-set torque threshold, the tool produces a sharp, distinct audible click and a physical break-away sensation, instantly alerting the operator to stop applying force and protecting delicate threads.
- 凸 (Convex/Male) Drive Anvil Engineering: The precision-machined 凸 (convex/male) square drive anvil features a secure spring-loaded ball detent mechanism. This ensures a wiggle-free, high-tolerance lock with the corresponding 凹 (concave/female) square drive pocket of standard manual industrial sockets, reducing energy loss and ensuring exact torque transmission.
Heavy-Duty Structural Metallurgy & Dual-Direction Utility
- Premium Heat-Treated Chrome Vanadium Steel Body: The outer structural tube is hot-forged from high-grade Chrome Vanadium (Cr-V) steel, subjected to a multi-stage thermal hardening process, and finished with a durable satin chrome layer. This rugged shield resists surface abrasion, drop shocks, and degradation from industrial oils and grease.
- Reversible Ratchet Head with Smooth Engagement: Features a integrated flip-lever directional switch on the ratchet head, enabling both clockwise torque measurement and counter-clockwise rotation. The fine-tooth ratcheting system allows for smooth operation in tight engine bays and cramped equipment cabinets with minimal swing clearance.
