Description

Impact Socket 12-Point 23mm 1/2-Inch Drive

Brief Overview

This 23mm 12-point impact socket is purpose-built for high-torque pneumatic impact applications. Manufactured from chrome-moly steel with a dark impact-grade finish, it delivers reliable performance in demanding automotive and industrial repair environments. The 12-point design reduces fastener rounding and increases engagement surface area compared to 6-point alternatives. Stock this size alongside complementary 22mm impact sockets and larger 30mm variants to round out your reseller's inventory.

Key Features

  • 12-Point Double-Hex Profile: Minimizes cam-out on bolt heads and fastener damage; ideal for both metric and standard bolt configurations
  • Chrome-Moly Steel Construction: Impact-rated material designed to withstand repeated high-torque strikes from pneumatic wrenches without cracking or deformation
  • 1/2-Inch Drive Compatibility: Universal fit with standard 1/2-inch drive ratchets, impact wrenches, and torque multipliers
  • Deep Socket Design: 78mm total length provides access to recessed fasteners and studs in tight engine compartments and chassis work
  • Retaining Pin Hole: Ball-detent or pin-retaining feature keeps socket secured on the drive square during use and transport
  • Matte Black Finish: Durable impact-grade coating resists corrosion and provides professional appearance
  • Silkscreen Markings: Part number and size clearly marked for easy identification in service kits

Business Advantages for Resellers

  • High Turnover Category: Impact sockets are wear-and-damage consumables; shops regularly replenish stock as fasteners round or sockets crack under impact stress
  • Margin-Friendly: Industrial impact sockets command stable retail pricing with 40–60% margin potential depending on volume
  • Bulk Purchase Incentive: Mechanic shops and service centers typically buy complete socket sets or multi-pack assortments—create bundled offers with smaller 12mm or 13mm impact sockets to increase order value
  • Cross-Sell Potential: 23mm is a frequently-used size; customers buying this socket often need complementary sizes for complete toolkit coverage
  • Professional Credibility: Chrome-moly impact sockets position your brand as serious industrial supply, not consumer-grade tools

Target Applications

  • Automotive Repair: Engine work, suspension fasteners, transmission pan bolts
  • Heavy Equipment Maintenance: Industrial machinery, construction equipment, fleet service
  • Pneumatic Tool Integration: Direct compatibility with impact wrenches rated for 1/2-inch drive
  • Professional Mechanic Workshops: Ideal for shops using air tools as the primary fastener-removal method

Why This Socket Matters

The 23mm size occupies a critical gap in metric fastener work—common on modern engine blocks, alternators, and brake components. The 12-point profile reduces rounding on chrome-plated and soft fasteners, extending tool life and reducing customer call-backs for stripped bolts. The deep design reaches recessed fasteners in modern vehicle architecture where shallow sockets cannot engage.

Stock this 23mm impact socket as a foundational SKU in your impact tool category. It moves regularly, pairs well with adjacent sizes, and represents the professional-grade inventory your reseller customers expect.
