Description

Extra-Long Ring Ratchet Spanner, 17mm, 72-Tooth Fine Gear, 435mm Length

Brief Overview

This extra-long ring ratchet spanner is engineered for mechanics and technicians who demand precision and reach. The 435mm extended length and asymmetrically offset 12-point ring head provide access to fasteners in tight, recessed locations where conventional spanners cannot fit. Built from Cr-V steel with a Cr-Mo ratchet insert, this tool delivers consistent performance across heavy industrial, automotive, and maintenance applications. The 72-tooth fine gear mechanism ensures smooth, controlled engagement with minimal ratchet play. Consider pairing this with complementary ratcheting wrenches or combination ring spanners to round out your technical toolkit.

Key Features

  • 72-tooth fine gear mechanism – Smaller gear increments (5° per tooth) reduce ratchet angle, enabling work in ultra-confined spaces
  • Asymmetrically offset 12-point ring head – Positions the working face at an optimized angle, reducing knuckle contact and improving user control
  • Reversible ratchet drive – Quick-flip lever switches between tightening and loosening without tool removal
  • Cr-V shank with Cr-Mo ratchet insert – Two-material construction balances durability and precise gear engagement
  • 435mm extra-long reach – Reaches deep-set fasteners in engine bays, transmission housings, and recessed mechanical assemblies
  • Swivel head design – Slight articulation at the pivot joint accommodates angled or obstructed fastener access
  • Polished chrome finish – Corrosion resistant, easy to clean, professional appearance

Business Advantages for Resellers

High Demand Profile: Extra-long ratcheting spanners command premium margins in professional shop markets. Mechanics working on modern vehicles, industrial machinery, and agricultural equipment actively seek these tools to reduce job time.

Durability & Repeat Revenue: The Cr-V/Cr-Mo construction withstands high-cycle use without gear wear. Tools rarely fail, but shops routinely upgrade or add complementary sizes—driving consistent reorders.

Niche Market Positioning: Not every distributor stocks 72-tooth fine-gear ratchet spanners. This tool positions you as a specialist supplier, justifying higher margins against mass-market competitors.

Bulk Order Opportunities: Tool rental shops, fleet maintenance operations, and OEM service centers purchase these in multiples. A single account order can move 5–10 units.

Why Professionals Choose This Tool

Mechanics in confined-space environments (engine compartments, transmission tunnels, hydraulic line assemblies) face repeated dead-stop fasteners. A standard ring wrench requires full rotations—often impossible. This ratchet spanner reduces ratchet angle to 5° increments, allowing work with minimal clearance. The extended 435mm length reaches fasteners buried deep in mechanical assemblies, eliminating the need for socket extensions or awkward contortions.

The asymmetric ring offset protects knuckles from abrasion on surrounding components, reducing fatigue and injury risk—critical for high-volume maintenance environments where worker safety directly impacts productivity.
