Product Description

Brief Overview

This 3/8-inch drive hex insert bit socket is engineered for precision fastening applications requiring extended reach and accuracy. The 300mm length makes it ideal for accessing recessed or deep-set hex fasteners in confined spaces—critical for automotive assembly, electronics manufacturing, and precision machinery work. For shops requiring multiple hex sizes, consider complementary socket options in larger drive sizes to round out your tool inventory.

Key Features

  • 6mm Hex Recess: Matches common metric fastener standards for assembly and disassembly operations
  • Extended 300mm Length: Reaches deep fasteners without additional extensions, reducing connection points and improving torque transfer
  • CR-V Socket Body: Chrome vanadium construction with bright chrome plating ensures corrosion resistance and durability in harsh shop environments
  • S2 Bit Material: Manganese-phosphated S2 steel bits deliver superior hardness and wear resistance for repeated use
  • Satin Finish Socket Head: Reduces glare and provides a professional appearance; knurled band enables secure hand grip without slipping
  • 3/8" Drive Compatibility: Connects seamlessly to ratchets, torque wrenches, and air tools using standard 3/8-inch square drive

Business Advantages for Resellers

  • Precision Market Appeal: Extended-length sockets command premium pricing in precision assembly and electronics sectors
  • Reduced Returns: CR-V with chrome plating and S2 bits minimize premature wear complaints
  • Cross-Sell Potential: Mechanics and technicians purchasing deep-reach sockets often need companion hex socket sets in alternate drive sizes for mixed fastener applications
  • Stock Efficiency: Single-size socket keeps inventory lean while filling a specific gap in mechanic toolkits

Why This Socket Matters

The 300mm length eliminates the need for stacking extensions, which saves setup time and preserves critical torque accuracy. The manganese-phosphated S2 bits resist stripping under load, while the CR-V body withstands the repeated impacts common in high-volume assembly lines. This is a workhorse tool for professional shops that demand reliability without premium pricing.
