Description

1/4-Inch Drive Ball-End Hex Bit Extension, 300mm Length, 4mm Tip

Overview

This 300mm ball-end hex bit extension delivers precise fastening control in confined or angled applications where standard straight bits cannot reach. The ball-end tip geometry allows 25-30° of angular working offset—critical for maintenance work on automotive, electronics assembly, and industrial machinery where space is constrained. The 1/4-inch drive socket integrates seamlessly with your existing bit and socket inventory, making this an essential inventory item for shops that service compact assemblies. Pair this with 1/4-inch hex bit sockets to build a complete angled-access fastening system.

Key Features

  • 300mm Extended Length: Reaches recessed fasteners in confined cavities without requiring additional extensions
  • Ball-End 4mm Hex Tip: Accommodates 4mm hexagonal fasteners; ball geometry permits working angles up to ~30° without slipping
  • 1/4-Inch Drive Socket: Female square recess with knurled retention band for secure bit seating
  • Hexagonal Matte-Grey Shaft: Uniform cross-section provides structural rigidity while the matte finish resists glare during precision work
  • Polished Silver Socket: Chrome-plated or bright-finished 1/4-inch drive receptacle with detent notch for tool retention

Business Advantages for Resellers

  • High-Margin Consumable Accessory: Extended-length bits have shorter service lives than sockets; drives repeat orders from professional shops
  • Compact Footprint: The slim 300mm profile fits standard socket trays and storage systems without requiring specialized bins
  • Cross-Sell Opportunity: Mechanics purchasing extended bits typically need compatible 1/4-inch sockets and bit sets; bundle pricing accelerates turnover
  • Essential for Specialty Work: Automotive electrical connectors, computer assembly, and medical device maintenance all depend on angled-access fastening—steady demand from these verticals
