3/8″ Drive 12-Point Long Hand Socket – Complete Size Range

Brief Overview

This 3/8″ drive long hand socket series delivers precision and control for fastening work requiring extended reach and fine engagement. The 12-point profile grips fastener heads securely with minimal rounding risk, while the satin chrome finish resists corrosion and maintains professional appearance across repeated shop use. The integrated knurled grip band—machined into the socket body—provides intuitive hand control without requiring a wrench handle, making these sockets ideal for confined spaces, assembly work, and situations where speed matters. For resellers stocking comprehensive fastening solutions, these complement both standard short hand sockets and full socket sets seamlessly.

Key Features

• 12-Point Internal Geometry: Engages fastener heads with four contact points per face, minimizing cam-out and head damage compared to 6-point alternatives
• Extended Length Design: 28–30mm overall lengths provide reach into recessed fastener pockets and tight assembly areas
• Satin Chrome Finish: Corrosion-resistant, professional appearance; easy to clean and maintain
• Knurled Grip Band: Machined texture positioned mid-body for secure hand control; eliminates need for a separate handle
• Precise Dimensional Accuracy: Machined dimensions (D1, D2, T, L) ensure tight, repeatable fits across the size range
• 3/8″ Square Drive: Universal compatibility with standard 3/8″ drive tools, extensions, and ratchets

Business Advantages for Distributors

• High-Margin Item: Hand sockets carry strong per-unit margins; customers often purchase multiple sizes, driving basket size upward
• Essential Stock: Size range (8–24mm) covers 90% of fastening applications in automotive, assembly, and maintenance sectors
• Repeatable Orders: Once customers stock these, they reorder consistently as sockets wear or are lost
• Low Inventory Risk: Chrome-plated, durable construction means minimal shelf life concerns or obsolescence
• Upsell Opportunity: Pair with pneumatic or manual ratchets, extensions, and impact-rated sockets for complete shop outfitting
