Description

3/8-Inch Drive 12-Point Long Hand Socket, 8–19mm Sizes

Brief Overview

This is a purpose-built long hand socket designed for mechanics and technicians who regularly work with recessed or deeply-seated fasteners. The extended 63mm length gives you the reach needed when standard sockets fall short, while the 3/8-inch drive pairs naturally with most professional ratchet and breaker bar combinations. The 12-point profile grips hex and double-square fasteners with precision, reducing rounding risk on damaged or worn hardware. If you stock deep-access hand socket sets, these individual sizes fill gaps and serve as direct replacements for worn pieces.

Key Features

  • 12-Point Internal Geometry – Engages hex and double-square fasteners at 30° intervals; minimizes slippage and prevents cam-out on compromised bolt heads
  • 3/8-Inch Square Drive – Compatible with industry-standard ratchets, breaker bars, and power tools in this drive class
  • Extended 63mm Length – Reaches recessed or deeply-set fasteners that standard sockets cannot access
  • Knurled Grip Ring – Textured band near the drive end improves hand control during manual operation
  • Matte Chrome Finish – Corrosion-resistant plating suitable for workshop and outdoor environments; clean, professional appearance
  • Closed-End Design – Fully enclosed working end prevents fastener slip-off and protects against contamination

Business Advantages for Resellers

  • Strong Margin Profile – Hand sockets carry healthy wholesale margins; competitive pricing against brand-name alternatives
  • Consumable Replacement Cycle – Sockets are worn, lost, or damaged regularly in active shops; expect repeat orders from the same customers
  • Versatile Appeal – Fits both DIY enthusiasts and professional technicians; market across multiple customer segments
  • Bulk Order Opportunity – Shops building or refreshing tool kits often order complete size ranges; offer volume pricing on 8–19mm sets
  • Complementary Cross-Sell – Bundle with ratchets, breaker bars, or socket organizers to increase transaction value

Technical Notes

  • Material – Plated steel construction; optimized for hand-tool service life
  • Drive Interface – Square recess machined to ISO 1174 tolerances for secure fit with 3/8-inch tools
  • Fastener Engagement – 12-point geometry suits both metric hex bolts and double-square (Robertson) fasteners common in automotive and industrial assembly

Why Choose This Over Standard Sockets

The extended length eliminates the need for socket extensions on recessed fasteners—reducing joint stress and improving accuracy. The 12-point profile is gentler on worn or soft-metal bolts than 6-point sockets, making these essential for restoration or salvage work.

Stock these individually or as a complete 8–19mm set to meet varied customer needs and secure repeat business.
