Industry Torque Wrench, 40-220 Nm, 1/2-Inch Drive, Click-Type

Brief Overview

This is a precision click-type torque wrench designed for professional mechanics and assembly technicians who demand reliable, repeatable torque control. The 40-220 Nm range positions it as a versatile workhorse for general automotive fastening, engine assembly, and industrial maintenance tasks. If your operation requires coverage across multiple torque ranges, consider pairing this with a precision torque wrench for lighter-duty applications or a heavy-duty model for high-torque industrial work.

Key Features

• Click-Release Mechanism: Audible and tactile "click" feedback when target torque is reached—eliminates guesswork and prevents over-tightening
• ±3% Accuracy: ISO 6789 certified precision ensures consistent, reliable torque application across production runs
• High-Alloy SCM440 Head: Hardened drive head resists wear and rounding, critical for high-volume fastening operations
• Durable Polymer Handle & Housing: Protective yet lightweight design with reinforced plastic construction for shock absorption
• Graduated Scale & Locking Ring: Clear Nm markings with blue adjustment collar and locking mechanism prevent accidental torque value changes
• 1/2-Inch Square Drive: Compatible with standard 1/2" sockets and accessories—broad availability of attachments
• 72-Tooth Ratchet: Smooth engagement and fine control with minimal angular increment between positions
• 510 mm Overall Length: Long enough for access in tight engine bays; manageable weight (1,194g) for extended use without fatigue

Business Advantages for Resellers

Volume & Margin Opportunity: This torque range (40-220 Nm) covers the majority of automotive fastening tasks—from wheel lug nuts to engine head bolts—making it a high-turnover SKU. Stock depth in this range typically justifies better wholesale pricing.

Customer Retention: Mechanics and shop owners recognize ISO 6789 certification and DIN compliance as marks of reliability. A tool that holds accuracy across thousands of cycles reduces customer callbacks and builds loyalty.

Complementary Sales: Pair with interchangeable-head torque wrench sets for shops needing multiple torque ranges without buying separate tools, or stock lighter and heavier models to serve the full spectrum of customer applications.

Professional Positioning: The click-type design is the industry standard for controlled assembly work. Unlike beam-type or digital alternatives, it requires no interpreter skill—even occasional users get consistent results.

Why This Tool Matters in Your Shop

A torque wrench is not optional—it's liability protection. Over-torqued fasteners strip threads, crack castings, and cause field failures. Under-torqued fasteners loosen, creating safety hazards. This wrench eliminates both risks by delivering predictable, repeatable torque every single time.

The 40-220 Nm window is the sweet spot for most work: passenger vehicle wheel service, engine assembly, brake system work, transmission pan bolts, and industrial equipment maintenance. The audible click is non-negotiable for high-volume environments where visual confirmation isn't always practical.

Stock this tool as a cornerstone of your fastening lineup. It's the tool professionals ask for by name, and it's one of the few items that justify repeat purchases due to normal wear and calibration drift over time.
