3/8″ Drive 12-Point Long Hand Socket – Deep Access Design
Brief Overview
This 3/8″ drive long hand socket delivers the extended reach needed for deep fastener access in tight engine bays, suspension work, and machinery assembly. The 12-point (double-hexagon) profile engages fasteners securely while minimizing corner rounding on delicate or stripped nuts and bolts. Built from chrome-plated steel with a knurled collar for controlled positioning, this socket handles precision work across the automotive, industrial, and equipment maintenance sectors. Available in a comprehensive size range from 8mm to 24mm, it pairs seamlessly with long-reach socket extensions and standard 3/8″ drive ratchets for maximum shop flexibility.
Key Features
- 12-Point Profile: Double-hexagon recess engages fastener flats precisely, reducing cam-out on stuck or corroded fasteners
- Extended Length Design: 28–30mm total length provides clearance in recessed or hard-to-reach mounting points
- Chrome-Plated Finish: Corrosion-resistant coating protects against workshop moisture and extends tool life
- Knurled Collar: Textured grip ring near the drive end ensures controlled hand positioning and prevents slipping during torque application
- Standard 3/8″ Drive: Compatible with all 3/8″ drive ratchets, extensions, and accessories—no adapter required
Why Resellers Choose This Range
Turnover & Margin: Long sockets command a 35–50% resale premium over standard-depth alternatives due to their specialized application. Stock depth, not breadth, drives customer loyalty.
Customer Retention: Once a technician discovers how a long socket solves a recurring access problem, repeat orders follow. These are not impulse purchases—they're solution-driven.
Complete Socket Coverage: The 8–24mm range covers 95% of metric fastener demand in automotive assembly, engine work, and light industrial maintenance. Resellers gain the ability to position themselves as a one-stop solution rather than directing customers elsewhere.
Low Defect Rate: Chrome-plated steel sockets have minimal field failures. Returns are rare, support costs are negligible, and customer satisfaction translates to glowing reviews.

Real-World Applications
- Automotive Assembly: Engine oil filter housings, thermostat covers, and exhaust manifold fasteners in confined spaces
- Suspension & Steering: Strut tower caps, tie-rod ends, and control arm mounting in tight underbody geometry
- Industrial Equipment: Bearing housings, motor mounts, and transmission mounting bolts where standard sockets cannot reach
- Precision Maintenance: High-value fasteners (aircraft hardware, medical equipment) that demand 12-point protection against deformation
