Description

3/8-Inch Drive 12-Point Long Hand Socket, 23mm, 63mm Length

Brief Overview

This 23mm long hand socket delivers the precision and durability your shop requires for demanding fastening tasks. The 12-point double-hex geometry provides superior grip on fasteners while reducing cam-out risk—a critical advantage when working with tight tolerances or damaged bolt heads. The extended 63mm length grants access to recessed fasteners in confined engine bays and tight assembly spaces. If you stock comprehensive 3/8-inch drive socket ranges or need specialized deep-access designs, this 23mm variant is an essential individual component for complete tool coverage.

Key Features

  • 12-Point Double-Hex Profile – Maximizes contact surface with fasteners; reduces rounding and slippage compared to 6-point designs
  • 3/8-Inch Square Drive – Compatible with standard ratchets, torque wrenches, and pneumatic impact tools
  • Long Format (63mm) – Reaches recessed fasteners in tight engine compartments and assembly fixtures
  • Knurled Grip Band – Centered knurling improves hand control and reduces slipping during manual operation
  • Matte Chrome Finish – Corrosion-resistant, professional appearance; withstands workshop environments
  • Precision Machined Construction – Tight tolerances on drive recess (D1: 31.6mm, D2: 27mm, T: 21mm) ensure secure coupling with drive tools

Business Advantages for Resellers

  • High-Turnover Size – The 23mm socket is a frequently-consumed item in automotive and industrial shops; regular restocking generates consistent order volume
  • Wide Tool Compatibility – Works seamlessly with all 3/8-inch drive ratchets, extensions, and impact tools already in customers' kits
  • Standalone & Bundle Appeal – Sells well as an individual replacement or as part of metric socket sets; positions your shop as a complete fastening solution provider
  • Low Inventory Footprint – Single socket requires minimal shelf space while commanding healthy margin on individual unit sales
  • Professional Durability – Chrome finish and precision machining ensure long service life, reducing customer returns and boosting reputation for quality

Application Context

This socket excels in scenarios where both reach and fastener grip are critical:

  • Engine Bay Work – Recessed spark plugs, valve cover bolts, and intake manifold fasteners
  • Transmission & Drivetrain Assembly – Access to deep-set fasteners without obstruction
  • Precision Mechanical Work – Applications where 12-point geometry prevents bolt rounding
  • Industrial Equipment Maintenance – Machine assembly and maintenance in confined spaces

The 23mm size addresses a core gap in many mechanics' tool kits—larger enough for substantial fasteners (automotive subframes, suspension components) yet small enough to access constrained areas where 22mm or 24mm sockets would not fit.


Stock this socket as both an individual replacement item and as part of your 3/8-inch drive socket set offerings. The combination of professional finish, proven 12-point geometry, and high-demand size ensures strong customer satisfaction and repeat orders.
