1/2-Inch Drive Torque Wrench, 70-350 Nm Range

Brief Overview

This 1/2-inch drive torque wrench delivers precision fastening for heavy-duty industrial and automotive applications. With a 70-350 Nm range and reversible left/right scale markings, it accommodates both standard and reverse-torque operations without tool switching. The micrometer-style adjustment collar provides fine-increment control, making it suitable for critical assembly tasks where accuracy is non-negotiable. For shops requiring broader torque coverage, consider pairing this with a torque wrench for lighter applications or a high-capacity model for heavy industrial work.

Key Features

• Reversible Needle Scale: Bidirectional markings for both clockwise and counterclockwise torque application
• 70-350 Nm Range: Covers high-torque fastening from medium to heavy-duty applications
• 10 Nm Scale Increments: Fine-resolution markings for precise torque setting
• Micrometer Adjustment Collar: Smooth, controlled torque setting with tactile feedback
• Quick-Release Ratchet Head: Red button mechanism allows rapid socket changes without resetting torque value
• Reversible Direction Lever: Integrated selector for switching ratchet drive direction
• Chrome-Plated Steel Shaft: Polished, corrosion-resistant construction for long service life
• Ergonomic Grip Handle: Textured grey rubber sleeve reduces hand fatigue during extended use
• Cr-V Construction: Chromium-vanadium steel components ensure durability under high-load conditions

Why Resellers Choose This Model

High Demand Range: The 70-350 Nm window captures a significant share of heavy-duty industrial fastening work—engine assembly, transmission rebuilds, frame construction, and structural bolting. This is a workhorse range that keeps your customers returning for stock.

Reversible Design Reduces SKU Count: Many competitors require separate clockwise and counterclockwise models. This reversible design eliminates the need to stock two variants, reducing inventory complexity while offering full functionality.

Professional-Grade Build: Cr-V construction and chrome plating signal quality to end-users. This justifies a premium price point compared to budget alternatives, protecting your margin.

Micrometer Precision: The adjustable collar mechanism appeals to shops performing critical assembly (engine work, hydraulic systems) where ±5% accuracy is mandatory. These customers will pay for reliability.

Bulk Order Opportunity: Most shops operating at this torque level need multiple units (engine bay, transmission station, frame welding). Stock depth here drives consistent repeat orders.
