Description

1/2-Inch Drive Extension Bar, 250mm Chrome Vanadium

Brief Overview

This 250mm extension bar is a core accessory for any professional socket set, designed to reach fasteners in confined or recessed spaces. Built from chrome vanadium steel with a polished chrome finish, it delivers the durability and corrosion resistance expected in high-volume shop environments. The spring ball detent on the male drive end ensures sockets stay seated during use, while the female socket end features a retaining pin hole for secure attachment. Perfect as a standalone purchase or bundled with socket sets for resale. Pair this with shorter 150mm extensions or longer 400mm bars to build a complete extension system for your customers.

Key Features

  • Chrome Vanadium Construction: Stamped material designation ensures tool steel durability and resistance to corrosion
  • 250mm Working Length: Bridges moderate distances without excessive flex or vibration
  • Spring Ball Detent: Keeps sockets firmly seated; prevents accidental release during operation
  • Polished Chrome Finish: Professional appearance with proven corrosion protection
  • Female Socket & Male Drive: 1/2-inch drive compatibility on both ends; retaining pin hole prevents loss in high-motion environments
  • Stepped Design: Center section reduces weight while maintaining structural integrity

Business Advantages

  • High-Margin Accessory: Extension bars carry strong markup potential when paired with socket sets or sold as standalone consumables
  • Essential for Every Shop: Professional mechanics require multiple lengths; the 250mm is a best-seller for general-purpose work
  • Bulk-Friendly Packaging: Lightweight, stackable inventory that maximizes shelf space ROI
  • Resale-Ready: Chrome finish and "CHROME VANADIUM" stamping give tools perceived quality that justifies premium pricing
  • Low Return Rate: This is a rock-solid product with no moving parts—expect minimal warranty claims
