Description

Long Double Ring Wrench, 16x18mm, 407mm Length, 12-Point Box-End

Brief Overview

This fixed, non-ratcheting double-end wrench delivers the reliability and precision demanded in professional automotive and industrial work. The 16x18mm configuration covers a common fastener pairing, while the extended 407mm shaft provides excellent reach for deep-set fasteners in engine bays and tight mechanical spaces. The 12-point box design minimizes cam-out risk and distributes load evenly across fastener corners. If you're stocking a comprehensive wrench collection, consider pairing this with smaller multi-purpose offset spanners and larger metric double-end wrenches to cover the full service spectrum.

Key Features

  • 12-Point Box Heads: Multi-point engagement reduces corner rounding and improves grip security on worn or damaged fasteners
  • Extended 407mm Shaft: Reaches fasteners in deep cavities, engine compartments, and confined mechanical spaces without requiring extension bars
  • Chrome-Plated Steel Construction: Mirror-polished finish resists corrosion and maintains professional appearance through years of workshop use
  • Single-Piece Design: No pivots, pins, or moving parts to fail; delivers solid, predictable torque transfer
  • Symmetrical Double-End Configuration: Both ends ready to work; eliminates tool-swapping delays on paired fastener sets

Why Resellers Profit from This Wrench

High-Velocity Stock Item:
Double-end wrenches are consumable-adjacent tools in fleet maintenance and independent shops—mechanics buy replacements regularly when fasteners strip or heads wear. The 16x18mm pairing is a top-request size for engine block work and transmission fasteners, ensuring quick turnover on bulk orders.

Margin-Friendly Category:
Hand tools, particularly metric wrenches in professional-grade finishes, command healthy markups. Shops expect to pay premium prices for chrome-plated, corrosion-resistant tools that last through seasons of heavy use.

Bundling Opportunity:
Stock this alongside similar 17x19mm wrenches and other metric double-ends to create complete "mechanic's metric wrench kits" that appeal to independent technicians and service departments building personal tool collections.
