3/8-Inch Drive 12-Point Long Hand Socket, 8–24mm Range

Overview

This extended-length 12-point hand socket series delivers precise fastener engagement across a comprehensive 8–24mm size range. Each socket features a knurled grip band for secure hand control and is finished in durable chrome for corrosion resistance. The 12-point design reduces cam-out risk compared to 6-point alternatives, making these sockets ideal for mechanics working with metric fasteners in confined spaces. Pair these with compatible shallow-access sockets or deep-drive variants to maximize your workshop flexibility.

Key Features

• 12-Point Internal Profile: Reduces rounding and cam-out, increasing engagement accuracy on metric fasteners
• Extended Length Design: Reaches fasteners in recessed or hard-to-access locations
• Knurled Grip Band: Textured surface near the drive end ensures positive hand control during use
• Chrome Finish: Corrosion-resistant coating extends tool life in demanding shop environments
• 3/8-Inch Square Drive: Compatible with standard ratchets, torque wrenches, and air tools in the 3/8" drive class
• Metric Sizing: Covers 8mm through 24mm—the most common fastener range in automotive and machinery work

Business Advantages for Resellers

• Complete Size Coverage: The full 8–24mm range eliminates customer callbacks for missing sizes, reducing inventory complexity
• Bulk Order Efficiency: Standardized dimensions and consistent manufacturing simplify stocking and restocking cycles
• Professional Appeal: 12-point design and extended reach position these sockets as premium hand tools, justifying competitive margins
• Low Return Rate: Precision-machined construction and durable chrome finish minimize warranty claims
• Cross-Sell Opportunity: Bundle with ratchets, torque wrenches, or impact-rated sockets to increase transaction value

Notes:

• D1 = Socket bore diameter (fastener grip point)
• D2 = Hex outer dimension
• T = Wall thickness
• L = Overall socket length (extended design)

Applications

• Automotive Repair: Engine, transmission, and suspension fastener work
• Machinery Maintenance: Industrial equipment assembly and disassembly
• Precision Assembly: Electronics and control system mounting where cam-out must be avoided
• Confined Space Work: Extended length reaches fasteners in recessed engine bays or tight mechanical compartments

Why Choose This Range

The 12-point profile on these sockets provides mechanical advantage over 6-point alternatives by distributing load across more contact points, reducing fastener damage and rounding risk. The extended length accommodates the real-world mechanic's need to reach bolts buried beneath components or in recessed pockets. Chrome finishing ensures longevity even in high-humidity or outdoor shop environments.

For resellers, this is a foundational tool line—one that builds customer loyalty through reliability and completeness. Mechanics return for replacements because these sockets perform.
