3/8-Inch Drive Hex Bit Socket, 6mm, 355mm Length, CR-V Steel

Brief Overview

This is a specialized hex bit socket designed for precision work on manual gearbox assemblies, particularly in 6-speed and 4-wheel drive applications. The extended 355mm length provides the reach required for deep-set fasteners on OEM output shafts. Built with CR-V socket material and hardened S2 steel bit, this tool delivers durability where standard sockets fall short. Whether you're stocking for transmission service shops or building OEM-equivalent tool kits, this hex bit addresses a specific, high-value repair segment. Pair this with 6mm hex bit sockets in larger drive sizes for comprehensive gearbox service coverage across your workshop.

Key Features

• 6mm Hex Tip – Matches OEM specification for output shaft fasteners
• 355mm Extended Length – Reaches fasteners in confined gearbox spaces
• 3/8" Drive Socket – Compatible with standard ratchet and drive tools
• CR-V Socket Body – Chromium-vanadium alloy resists wear and deformation
• S2 Steel Bit – High-carbon steel provides impact resistance and longevity
• OEM Equivalent – Matches T10107A specification for 6-speed manual and 4WD applications (OA5, 02N gearboxes)

Business Advantages

This is a niche tool with consistent demand in transmission service and OEM repair environments. Shops specializing in manual gearbox work—particularly VW, Audi, and European 4WD platforms—require this exact specification regularly. The extended length eliminates the need for extension bars, reducing setup time and improving accuracy. Stock this as a premium service offering to command higher labor margins on transmission work. The OEM equivalence means it's a direct replacement, reducing customer hesitation on specialized tooling.

Real-World Application Context

This tool is purpose-built for transmission service specialists. The 355mm length is not arbitrary—it's engineered for the specific depth and angle of output shaft fasteners in European manual gearboxes. Mechanics working on VW Group platforms (Volkswagen, Audi, Skoda) will recognize this immediately as essential inventory. The CR-V/S2 combination ensures the tool resists cam-out and bit breakage under the moderate-to-high torque applied to gearbox fasteners. This is not a general-purpose hex bit; it's a specialized service tool with proven demand.

Call to Value

Stock this hex bit for mechanics and shops handling transmission service contracts. The specificity of the design—the exact length, drive size, and material combination—means customers cannot substitute generic alternatives. This creates a reliable, repeatable revenue stream with minimal return risk. Position it alongside transmission fluid and filter kits for bundled service packages that increase average order value.
