Description

Hex 2mm Screwdriver Bit, 25mm Length, 1/4-Inch Drive

Brief Overview

This is a precision hex screwdriver bit designed for driving small hex-socket fasteners in confined spaces and light-duty applications. The 2mm hex profile suits miniature bolts and set screws commonly found in electronics assembly, precision machinery, and automotive trim work. The compact 25mm overall length makes it ideal for tight access areas where standard bits won't fit. Available in various sizes including larger 4mm hex bits and extended 50mm alternatives for different job requirements.

Key Features

  • 2mm Hex Profile – Precision fit for small hex-socket fasteners and set screws
  • 1/4-Inch Drive Shank – Standard quick-change compatibility with power drills and impact drivers
  • 25mm Compact Length – Reaches into tight, confined spaces where standard bits cannot access
  • Heat-Treated Steel Construction – Hardened for durability and consistent performance across repeated use
  • Chamfered Edges – Prevents chuck slipping and reduces wear on driver connections
  • Matte Finish – Professional appearance with corrosion-resistant surface treatment
