Description

3/4-Inch Drive Impact Extension Bar, 100mm Length

Brief Overview

This 3/4-inch drive impact extension bar is purpose-built for high-torque fastener work in automotive, industrial, and heavy equipment service. The 100mm length provides compact reach while maintaining rigid contact with impact sockets—ideal for tight spaces where standard extensions fall short. Forged from chrome molybdenum steel and finished with a dark phosphate coating for corrosion resistance, this extension delivers the durability professional shops demand. When you need extended reach without sacrificing control, pair this bar with longer impact extension options or build a complete 3/4-inch drive system with heavier-duty impact tools for maximum versatility.

Key Features

  • Chrome Molybdenum Construction: Engineered steel alloy rated for impact loading without permanent deformation
  • 3/4-Inch Square Drive: Matches standard heavy-duty impact sockets and tools for seamless integration
  • 100mm Compact Length: Optimized for confined work areas while maintaining sufficient moment arm
  • Dark Phosphate Finish: Industrial protective coating resists rust and wear
  • Precision Socket Interface: Deep female drive socket with thick walls prevents rounding or damage
  • Retaining Pin Hole: Drilled hex male end secures the extension to socket sets or tool racks
