3/8-Inch Drive 6-Point Long Hand Socket – Professional Deep Socket Series

Brief Overview

This 3/8-inch drive 6-point long hand socket is engineered for precision mechanical work where fastener accessibility is critical. The extended length (63mm) allows technicians to reach recessed or deeply seated nuts and bolts that standard-depth sockets cannot access. The six-point internal geometry minimizes cam-out and distributes load evenly across fastener corners, reducing the risk of rounding. Chrome-plated finish provides corrosion resistance in demanding shop and field environments.

For comprehensive socket coverage, consider pairing with complementary 3/8" drive socket sets to build out a complete fastener toolkit.

Key Features

• 6-Point Internal Geometry: Precise hex profile engineered to prevent cam-out during torque application, protecting fastener integrity.
• Extended Length Design: 63mm overall length reaches recessed fasteners in confined spaces—critical for engine work, suspension assembly, and tight assembly scenarios.
• 3/8-Inch Drive Compatibility: Works seamlessly with standard 3/8" ratchets, torque wrenches, and pneumatic tools across professional shops.
• Chrome-Plated Finish: Durable metallic coating resists corrosion and oxidation in wet, salt-laden, or high-humidity environments.
• Knurled Grip Ring: Textured band on socket exterior improves tactile control and reduces slipping during hand-ratchet operation.
• Size Range: 8mm–24mm: Covers the majority of automotive and machinery fasteners; individual sizes available for targeted inventory management.

Business Advantages for Resellers

• High-Velocity SKUs: Socket tools drive consistent repeat orders from mechanics and technicians who rotate inventory seasonally.
• Complete Size Range: Offering 8mm through 24mm provides flexibility to stock individual sizes or full sets, accommodating both bulk and boutique customer orders.
• Professional-Grade Durability: Chrome-plated construction withstands heavy commercial use, generating positive customer reviews and reducing warranty claims.
• Margin-Friendly: Low material cost relative to selling price supports healthy distributor margins on bulk orders.
• Cross-Sell Opportunity: Pair with ratchets, extensions, and additional 3/8" drive socket variants to increase basket size per transaction.

Design Rationale & Applications

The 6-point socket geometry is the professional standard for controlled fastener engagement. Unlike 12-point variants (which prioritize speed), the 6-point design contacts only the fastener's critical load-bearing corners, preventing slippage and fastener damage. The extended 63mm length is purpose-built for scenarios where bolt heads sit deep within recesses—engine bay work, transmission housings, suspension brackets, and industrial machinery assembly all benefit from this reach advantage.

The knurled grip ring serves a practical function: it prevents the socket from rotating against the palm during hand-ratchet work, improving work speed and reducing hand fatigue during high-volume fastener removal or installation.

Why This Tool Matters to Your Customers

Mechanics and technicians choose long sockets when standard depths fail. The consequence of undersizing—a rounded fastener—triggers expensive shop labor to extract the damaged bolt. This socket's 6-point geometry actively prevents that scenario, protecting both the fastener and the technician's reputation. For resellers, stocking this size range signals to customers that you understand professional-grade tool requirements.
