Description

21mm Hex Extra Reach Socket Wrench with Sliding T-Bar Extension and Universal Joint

Brief Overview

This is a purpose-built extra-reach socket wrench designed for mechanics who need extended access to fasteners in confined or recessed spaces. The sliding T-bar handle combined with a telescoping shaft allows you to reach fasteners that standard sockets cannot access. The universal joint enables work at angles without cam-out risk. If your inventory requires coverage across multiple sizes, consider stocking smaller hex socket extensions and larger 22mm variants to serve the full range of applications your customer base demands.

Key Features

  • Telescoping Design: Shaft slides and locks via dual rubber collar stops, extending from 230mm to 485mm for maximum reach flexibility
  • Universal Joint: Swivel connection allows angled fastening without binding or rounding the fastener corners
  • 6-Point Hex Socket: 21mm socket head optimized for grip and minimal cam-out on standard metric fasteners
  • T-Bar Handle: Squared drive interface accommodates standard handle attachments for leverage
  • Chrome-Plated Finish: Polished metal construction resists corrosion and withstands shop environment wear
  • Compact Stowed Position: Collapses to 230mm for storage and transport when reach adjustment isn't needed

Business Advantages for Resellers

  • High-Utility Product: Solves a specific pain point (fastener access in tight spaces), making it a logical add-on to socket sets and extension kits
  • Professional Segment: Targets serious mechanics and service shops where margin on specialty tools is strong
  • Repeatable Orders: Mechanics quickly discover the utility and reorder or recommend to colleagues
  • Completes Socket Ranges: Positions as an essential complement to standard socket collections, particularly for European metric fastener applications

The 21mm size targets common European metric fasteners on mid-to-large engine components and transmission housings.
