Description

Long Double Ring Wrench, 21x23mm, 431mm Length, 12-Point Chrome Molybdenum

Brief Overview

This long double ring wrench combines extended reach with dual 12-point closed box-ends, making it essential for mechanics working in tight engine bays, transmission housings, and industrial assembly lines where standard wrenches cannot access fasteners. The extended 431mm shaft provides significant mechanical advantage while the chrome molybdenum construction ensures durability under sustained torque. Whether you're stocking a professional garage or outfitting an industrial maintenance team, this wrench delivers reliability that justifies repeat orders. If your customers work with multiple fastener sizes, complementary tools like our compact double ring wrench in 8x10mm and medium-duty 17x19mm option round out a complete kit.

Key Features

  • 12-Point Closed Box-Ends: Precise engagement prevents rounding and cam-out, protecting fastener heads and reducing maintenance downtime
  • Extended 431mm Length: Reaches fasteners in recessed cavities, under manifolds, and other confined spaces where standard wrenches fail
  • Chrome Molybdenum Steel: High-strength alloy resists flexing under heavy load and withstands repeated high-torque cycles
  • Offset Ring Design: Both ends are angled relative to the shaft for improved knuckle clearance and ergonomic access
  • Polished Mirror Finish: Professional appearance, easy to inspect for damage, and resists corrosion in demanding shop environments
  • Dual 21x23mm Sizing: Two different wrench sizes on one tool eliminates fumbling and reduces tool kit bulk

Business Advantages for Resellers

  • High Perceived Value: The extended length and chrome molybdenum construction command premium pricing without proportional cost increases
  • Professional Positioning: Mechanics recognize this as a serious tool; stock it prominently to attract quality-conscious buyers
  • Bulk Order Ready: 21x23mm is a common fastener size in automotive and industrial applications—ensure adequate inventory for repeat customers
  • Cross-Sell Opportunity: Pair with smaller offset wrenches to build complete wrench collections that drive customer loyalty and multiple transactions
  • Durability = Repeat Business: Chrome molybdenum strength means fewer warranty returns and long shelf life for unsold units
