Description

Hand Socket 1/2-Inch Drive 6-Point 18mm

Brief Overview

This 18mm 6-point hand socket is a precision-engineered fastening tool designed for professional automotive and industrial work. The 6-point profile provides controlled engagement with hex fasteners, minimizing cam-out and rounding damage—critical advantages over 12-point designs when working with corroded or damaged bolt heads. Built from hardened chrome-plated steel with a satin finish, it delivers consistent performance across high-volume service environments. The knurled grip band ensures secure handling, while the standardized 1/2-inch drive connection pairs seamlessly with ratchets, extensions, and impact tools. This size sits in the mid-range of socket applications, making it essential for engine work, suspension assembly, and general fastener removal. Consider pairing this with complementary smaller drive sockets or larger capacity alternatives to build out a complete socket set for your service bay.

Key Features

  • 6-Point Internal Geometry: Reduced contact stress on fastener corners; ideal for vintage hardware and bolt heads showing wear
  • Chamfered Open End: Guides fasteners smoothly into engagement without binding
  • Knurled Grip Band: Textured mid-body surface prevents slipping during manual ratcheting
  • Chrome-Plated Finish: Corrosion resistance and professional appearance maintained across repeated use cycles
  • Standardized 1/2-Inch Drive: Full compatibility with all 1/2" drive ratchets, breaker bars, extensions, and pneumatic impact wrenches
  • Compact 38mm Length: Balanced design—long enough for access without excessive overhang on compact fastener clusters

Business Advantages for Distributors

  • High Turnover Tool: 18mm is a frequently-used size across automotive service, HVAC installation, and industrial maintenance—consistent demand across customer base
  • Bulk Order Opportunity: Metric socket sets are incomplete without mid-range sizes; resellers can position this as an essential upgrade or replacement unit for worn collections
  • Durability Profile: Chrome-plated steel resists corrosion in damp service environments, reducing early failure complaints and repeat returns
  • Margin-Friendly: Lower material cost than specialty sockets; acceptable markup allows competitive pricing without eroding profitability

Real-World Application Context

The 18mm socket addresses fasteners common in mid-sized engine components, transmission pan bolts, and structural assembly work. Its 6-point design is particularly valuable when servicing older vehicles where fastener heads have lost sharp edges—the reduced contact angle prevents additional damage. The 38mm length works well in confined spaces without requiring extension bars, improving access around engine bay crowding and under-dash installations.
