Description

Double-Ended Box Wrench, 7x9 mm, 12-Point Offset Design

Brief Overview

This is a precision-engineered double-ended box (ring) wrench combining 7 mm and 9 mm heads in a single, compact tool. The offset geometry and 12-point profiles ensure secure engagement with metric fasteners while minimizing cam-out risk. Whether your customers are working on small engine assembly, precision machinery maintenance, or automotive electronics, this wrench delivers the accuracy and reliability they need. Consider pairing this with our smaller metric box wrench options or larger capacity variants to build a comprehensive metric wrench collection for your inventory.

Key Features

  • Dual-size heads: 7 mm and 9 mm sizes on a single tool, reducing inventory bulk
  • 12-point ring design: Multi-point profile grips fasteners securely without slipping or rounding corners
  • Offset heads: Angled geometry provides knuckle clearance in tight or recessed work areas
  • Plated/coated finish: Durable copper/bronze finish resists corrosion and extends tool life
  • Compact, balanced construction: Lightweight design reduces fatigue during repetitive assembly tasks
  • Stamped size markings: Clear labeling ensures quick tool identification on the workbench

Business Advantages for Resellers

This wrench addresses a critical gap in small-metric tool kits. Technicians and assembly shops consistently need 7×9 combinations for precision work, yet many suppliers treat this size range as "too small" to stock properly. Stock this SKU and you'll capture demand from:

  • Precision assembly shops building electronics, small engines, or instrumentation
  • Automotive mechanics working on fuel injection systems and sensor brackets
  • Maintenance technicians requiring ergonomic tools for confined spaces
  • OEM assembly lines where standardized metric tooling is non-negotiable

The dual-head design also reduces customer SKU sprawl—one tool replaces two, improving perceived value and customer loyalty.
