1/2" Drive 12-Point Long Hand Socket

Brief Overview

This 1/2" drive 12-point long hand socket series delivers reliable, precision engagement for a full spectrum of fastener sizes—from 8mm to 36mm. The extended length provides superior reach and leverage in confined engine bays and assembly work, while the 12-point profile ensures positive grip on metric fasteners. Chrome-plated construction resists corrosion and maintains appearance through heavy shop use. For mechanics requiring maximum versatility, 6-point long hand sockets offer an alternative grip style for situations where torque demand is critical.

Key Features

• 12-Point Internal Profile: Provides rapid engagement and re-engagement of metric fasteners; ideal for speed in high-volume fastening work.
• Extended Length Design: 77mm standard length (up to 85mm for larger sizes) enables access in deep engine cavities and complex assemblies.
• Chrome-Plated Finish: Polished, reflective coating delivers corrosion resistance and professional appearance across thousands of cycles.
• Knurled Grip Band: Tactile knurling near the drive end ensures confident hand control, even in oily conditions.
• Chamfered Entry: Precision-cut socket mouth guides fasteners smoothly into the 12-point cavity, reducing rounding and operator fatigue.
• Complete 8-36mm Coverage: 18 individual sizes eliminate guesswork on metric job sites.

Why Distributors Stock This Range

Turnover & Profit Margin: 12-point sockets generate steady repeat orders from shops running high-volume metric assembly lines. The extended length justifies a premium price point while remaining competitive against inferior imports.

Customer Stickiness: Mechanics working European and Japanese vehicles depend on metric socket coverage. Stocking this full range positions you as the go-to supplier for serious shops—they won't hunt elsewhere.

Minimal Returns: Chrome-plated construction and precision manufacturing mean durability. Few warranty claims translate to higher net margin.

Bulk Order Incentive: Buy the complete 18-piece range (8mm through 36mm) and offer shops a "metric master set" package. Distributors who bundle this series see 2-3x order frequency versus single-size selling.

Why the 12-Point Profile Matters

The 12 contact points engage metric fastener flats more frequently than 6-point alternatives, reducing the chance of cam-out and fastener rounding—a critical advantage when working with aluminum or soft-metal fasteners common in modern engines. This translates to fewer callbacks and stronger customer loyalty for the shops you supply.

The extended 77mm length (standard across most sizes, 85mm for 34-36mm) provides clearance in turbocharged engine bays where heat shields and manifolds crowd the workspace. Mechanics appreciate the reach without sacrificing driver control.

Recommended Order Strategy

• Starter Pack: Stock sizes 10, 12, 14, 16, 17, 19, 21, and 24mm—these cover 70% of metric fastening across automotive and industrial assembly.
• Full Range Commitments: Bulk orders of the complete 18-piece set unlock volume pricing and position you for exclusive shop partnerships.
• Cross-Sell Opportunity: Pair this series with alternative 6-point long hand sockets for shops requiring maximum torque application or specialty fastener work.

Bottom Line

This is a workhorse socket series built for high-volume shops that value both speed and reliability. Chrome durability, precision engineering, and metric completeness make it a core inventory item that drives repeat business and separates your distribution operation from commodity competitors.
