3/8-Inch Drive 12-Point Long Hand Socket

Brief Overview

This 3/8-inch drive long hand socket delivers extended reach for fastener access where standard sockets fall short. The 12-point (double-hex) profile grips both hex and spline fasteners securely, reducing cam-out risk during assembly and removal. Available in 11 size increments from 8mm to 19mm, this socket covers the most frequently demanded metric fastener range. The knurled grip band near the drive end ensures confident hand control without slipping, critical for precision work in automotive assembly, maintenance, and industrial applications. Pair these with complementary long-reach socket sets for comprehensive shop coverage.

Key Features

• 12-Point Internal Profile: Engages both hex and 12-point fasteners with minimal point stress
• Extended Length Design: 63mm overall length provides superior reach into recessed fastener locations
• Knurled Grip Band: Machined texture near the drive end for secure hand control and tactile feedback
• Precision Machined Construction: Chrome-finish metal body with clean, stamped identification marking
• 3/8-Inch Square Drive: Direct compatibility with standard 3/8" ratchets, extensions, and pneumatic tools
• Size Range: 8mm through 19mm covers metric fasteners across most automotive and light industrial applications

Business Advantages for Resellers

Stock Efficiency: The 11-size range covers approximately 80% of metric fastener demand without requiring full socket set inventory. Resellers can stock individual sizes based on customer base demand, minimizing dead stock while maintaining availability.

Margin Opportunity: Long-reach sockets command a premium over standard sockets due to their specialized application. The extended design justifies higher retail pricing while remaining competitive against imported alternatives.

Repeat Business Potential: Mechanics and technicians purchasing individual sizes for their personal toolkits represent consistent, transaction-based revenue. Long-reach tools are often replaced more frequently than standard sockets due to intensive use in confined-space work.

Professional Positioning: Offering extended-reach variants signals to your customer base that you understand shop-floor requirements and specialized access challenges, strengthening customer loyalty.

Practical Applications

• Automotive Assembly & Repair: Access fasteners in engine compartments, transmission housings, and brake systems where depth clearance is limited
• Precision Mechanics: Extended reach eliminates the need for multiple extensions, reducing assembly time and improving torque accuracy
• Industrial Maintenance: Ideal for machinery fastener access where standard socket depth creates interference

Reseller Value Statement

Stock this socket range as a specialized offering that complements your standard socket inventory. The extended design addresses a specific market need—shops performing precision work in confined spaces—and justifies premium pricing. Individual size purchases, paired with extended-reach socket accessories, create natural upsell opportunities and position your inventory as solutions-focused rather than commodity-driven.
