Description

18mm Hex Extra Reach Socket Wrench with Sliding T-Bar, Universal Joint, 434mm Reach

Brief Overview

This is a specialized extension tool designed for accessing fasteners in hard-to-reach locations where standard sockets and wrenches cannot fit. The 434mm maximum reach combined with the universal joint swivel capability makes it ideal for tight engine bays, machinery assemblies, and industrial maintenance work. The sliding T-bar mechanism allows length adjustment from 200mm to 434mm, giving you flexibility across multiple job scenarios. If you work with smaller hex sizes, we also stock 10mm and 8mm hex reach extensions that follow the same proven design.

Key Features

  • 434mm Maximum Reach – Accesses deeply recessed fasteners without disassembly
  • 200mm Collapsed Length – Compact storage and maneuverability in confined spaces
  • 6-Point Hex Socket (18mm) – Secure grip on fasteners, reduces rounding risk
  • Universal Joint Swivel – Angles up to accommodate non-perpendicular fastener orientation
  • Telescoping Design with Stop Collars – Precision length control; black polymer collars prevent over-extension
  • Chrome-Plated Finish – Corrosion resistance and durability in workshop and field conditions
  • 14mm Shaft Diameter – Rigid construction withstands moderate torque loads

Business Advantages for Resellers

High-Margin Accessory: This extension tool pairs naturally with socket sets, ratchets, and power tools—customers who buy sockets inevitably need reach extensions. Stock multiple sizes to increase average transaction value.

Recurring Demand: Maintenance technicians and repair shops require these regularly. The sliding mechanism and universal joint experience wear over time, creating replacement demand within 2–3 years of regular use.

Complements Existing Inventory: If you stock hex socket sets in the 6mm–21mm range, this extension fills a critical gap in your service offering. Customers expect reach solutions when buying sockets.

Durable B2B Product: At 598g with chrome plating, this tool survives years of heavy use. Low warranty return rates mean better margins and customer satisfaction.

Recommended Use Cases

  • Engine Assembly & Maintenance: Reaching spark plugs, oil drain plugs, and fuel injectors in tight engine bays
  • Machinery & Industrial Equipment: Accessing bolts in confined assembly spaces
  • Automotive Restoration: Working in cramped vintage engine compartments
  • HVAC & Plumbing Installation: Fasteners in wall cavities and tight mechanical spaces

Stock this in your catalog as a professional-grade reach extension. The 18mm size targets mid-range fastening tasks—neither too small nor too large. Pair it with our 17mm and 21mm hex reach extensions to offer a complete range across common industrial sizes.
