Description

1-Inch Drive Impact Extension Bar, 100mm Length

Brief Overview

This 1-inch drive impact extension bar is engineered for professional shops and distributors who need reliable reach on high-torque applications. The 100mm compact length makes it ideal for working in tight engine bays and confined assembly areas where standard sockets won't fit. Built with impact-rated construction, this adapter maintains full torque transfer without deflection or wear. Stock this alongside longer 1-inch drive extensions and 3/4-inch drive impact bars to cover the full range of customer needs.

Key Features

  • 1-inch Square Drive: Full compatibility with 1-inch drive sockets and impact tools
  • 100mm Compact Length: Designed for precision work in restricted access areas
  • Black Oxide Finish: Corrosion-resistant, professional appearance; standard for impact-rated tools
  • Precision Pin Hole: Retaining pin socket for secure tool coupling
  • Heavy-Duty Construction: Impact-rated for pneumatic and cordless impact tools
  • 54mm Outer Diameter: Optimized balance between strength and maneuverability

Why This Matters for Your Business

Resellers benefit from stocking multiple drive sizes and lengths. The 100mm extension fills a critical gap—many shops need both compact reach (this tool) and extended reach (16-inch variants). Customers working on modern engine assemblies, transmissions, and suspension components frequently demand this exact specification. Your margin improves when you can fulfill complete tool kits without sending customers elsewhere.
