Description

Head-Interchangeable Torque Wrench & Spanner Set, 40–220 Nm Range

Brief Overview

This modular torque wrench system combines a precision click-type mechanism with 10 interchangeable spanner heads, delivering accurate fastening control across a 40–220 Nm range. Built for shops that prioritize efficiency without sacrificing precision, the interchangeable head design eliminates the need for multiple wrenches while maintaining ISO 6789 compliance. Whether you're managing high-volume assembly operations or precision-critical work, this set reduces tool inventory costs and setup time. For operations requiring additional coverage, consider pairing this with a needle-style variant for sensitive assemblies or a standard fixed-head torque wrench for simplified workflows.

Key Features

  • Interchangeable Spanner Heads: 10 open-ended fork heads (13, 14, 15, 17, 19, 22, 24, 27, 30 mm) eliminate the need to stock multiple torque wrenches for different fastener sizes
  • Precision Click Mechanism: Audible and tactile "click" feedback at set torque value ensures operator confirmation and repeatable accuracy
  • ISO 6789 Certified Accuracy: ±3% tolerance (±6.6–6.6 Nm across the range) meets or exceeds automotive and industrial assembly standards
  • Aluminum Body Construction: Lightweight yet rigid housing protects internal compression spring and disconnecting mechanism from shop environment wear
  • 1 Nm Graduation Resolution: Fine-tuned adjustments for critical fastening operations
  • 1/2-Inch Square Drive Ratchet Head: Universal compatibility with standard ratchet tooling
  • Organized Carrying Case: Molded foam insert organizes wrench and all heads for job-site transport and tool control
  • Calibration Certificate Included: Documentation of factory testing and calibration for traceability

Business Advantages for Resellers

Stock Efficiency: One modular wrench replaces 10 fixed-head units, reducing shelf space and capital tied up in redundant inventory.

Margin Opportunity: Interchangeable systems command premium pricing; the included calibration certificate and molded case justify higher retail positioning.

Customer Retention: The modular design encourages repeat purchases of replacement heads when worn, creating a consumable-adjacent revenue stream without the inventory burden of full wrench units.

Workshop Appeal: Professional shops appreciate reduced tool redundancy and faster setup times—key selling points for your B2B clientele.

Why This Matters for Your Customers

Shops operating high-throughput assembly lines—automotive fastening, HVAC installation, equipment manufacturing—depend on rapid head changes without sacrificing measurement reliability. The interchangeable head design cuts setup time between different fastener sizes while the ±3% accuracy maintains the precision required for critical assemblies. The included calibration certificate provides documentation for ISO-audited facilities, a non-negotiable requirement in regulated industries.

The aluminum body and compression spring mechanism ensure consistent click feedback across thousands of tightening cycles, extending tool life and protecting your shop's reputation for quality.
