1/4-Inch Drive 12-Point Long Hand Socket, 4–14mm Sizes

Brief Overview

This 1/4-inch drive long hand socket delivers the precision engagement needed for detailed mechanical work. The 12-point design grips fasteners securely while minimizing the risk of cam-out—a critical advantage when working with metric fasteners in confined spaces. The extended length provides access to recessed or hard-to-reach fasteners without requiring additional extensions. Whether you're stocking a general repair shop or supplying technicians with precision hand tools, this socket bridges the gap between basic coverage and professional-grade reliability. For shops preferring six-point profiles, six-point variants are also available, while larger 3/8-inch drive alternatives suit heavier-duty applications.

Key Features

• 12-Point Internal Profile: Provides multiple contact points for secure fastener engagement; reduces the likelihood of stripping or cam-out compared to 4-point designs.
• Extended Length Design: Long-reach format accesses fasteners in recessed mounting points, engine bays, and tight compartments without extension bars.
• 1/4-Inch Square Drive: Standard compatibility with 1/4-inch ratchets, torque wrenches, and hand-drive extensions; connects seamlessly to any 1/4-inch drive tool.
• Chrome Plated Finish: Corrosion-resistant surface maintains appearance and functionality across multiple cleaning cycles; resists light rust in standard workshop environments.
• Knurled Grip Band: Textured ring near the drive recess improves finger grip and control during manual hand-ratcheting operations.
• Metric-Sized Range (4–14mm): Complete coverage of common metric fasteners used in automotive, machinery assembly, and precision mechanical work.

Business Advantages for Resellers

• Essential Precision Tool: Metric socket sets are fundamental to any professional shop's inventory. The 4–14mm range covers the majority of common fastener sizes, making this a high-turnover item.
• Bulk Order Efficiency: Available in 13 individual sizes allows resellers to stock full sets or curate assortments tailored to specific customer bases (automotive, machinery, light industrial).
• Durability & Repeat Sales: Chrome-plated construction withstands repeated use and cleaning cycles; customers return to replenish worn or lost individual sockets.
• Competitive Positioning: 12-point design appeals to precision-focused shops and technicians who value fastener protection; position as a step above budget alternatives.
• Stackable SKU Strategy: Market individual sizes to customers with specific needs, or bundle into complete sets for higher average transaction value.

Practical Applications

• Automotive Repair: Accessing engine bay fasteners, fuel injector sockets, and brake component work where space is limited.
• Machinery Assembly & Maintenance: Metric fasteners in industrial equipment, conveyors, and automated systems.
• Electronics & Precision Work: Compact size suits work on smaller equipment, control panels, and assemblies where over-torque is a risk.
• Technician Hand-Tool Kits: Essential for mobile service calls and field work where ratchet extensions must be minimized.

Why This Socket Matters

The 12-point design is not merely aesthetic—it's engineering. Where a 4-point socket contacts fasteners at four corners (higher stress concentration), the 12-point distributes force across twelve engagement surfaces. This reduces rounding risk on corners and extends fastener life, which directly translates to customer satisfaction and fewer service complaints. The extended length eliminates the need for additional extension bars in most applications, reducing tool fatigue and improving access in tight work areas. For resellers, this means fewer returns due to stripped fasteners and higher perceived value in customer reviews.
