Lock-Up Micro Torque Wrench (Lock-Up Type Long Plastic Handle Series) is a high-capacity, heavy-duty mechanical fastening instrument engineered for demanding commercial vehicle repair bays, heavy plant machinery assembly lines, structural infrastructure projects, and marine engineering workshops. Designed for high-leverage operations across 3/4″ and 1″ square drive standards, this premium series features a solid, single-piece structural beam layout combined with a next-generation ergonomic plastic handle setup. By integrating a secure pull-down or push-to-lock collar system rather than a standard end-knob setup, this long-reach clicker wrench line completely isolates the chosen torque setting from accidental hand rotation during high-torque applications.

Feature
Ergonomic Shock-Absorbing Plastic Grip & Positive Collar Lock-Up
The interface design and safety features of this extended wrench series are built for harsh industrial environments:
- High-Impact, Chemical-Resistant Plastic Handle: Replaces traditional cold all-steel handles with a specialized, dual-material engineered polymer grip. This composite layout insulates the technician’s hands against freezing workshop temperatures, dampens vibration feedback during sudden torque releases, and resists chemical melting or structural cracking when exposed to brake fluid, oil, or industrial degreasers.
- Positive Mechanism Lock-Up Collar: Features a mechanical push-pull locking sleeve ring positioned at the forward edge of the composite grip. Once the worker rotates the handle to line up the exact value on the high-contrast laser-etched scale, the lock-up collar snaps forward, keeping the micrometer setting locked tight regardless of glove friction or twisting force.
- Distinct Mechanical Audile Click Cycle: Houses an internal micro-tempered spring assembly that delivers clear tactile and audible feedback. The moment the tool reaches the exact target limit, the internal block clicks sharply, notifying the technician to immediately cease applying force to protect bolt threads.
凸 (Convex/Male) Drive Configuration & Solid Single-Piece Steel Chassis
- Continuous Single-Piece Rigid Tube: Built as a single, unbroken solid structural steel beam with no detachable extension bars or pin joints. This configuration prevents structural flexing under extreme mechanical loads, ensuring accurate torque delivery to the fastener.
- High-Tolerance 凸 (Convex/Male) Anvils: The heavy-duty geared ratchet head features a solid 3/4″ or 1″ 凸 (convex/male) drive anvil with a spring-loaded friction retention ball. This establishes a tight connection with the corresponding internal 凹 (concave/female) square drive socket pocket of manual sockets, reducing mechanical play and power loss.
