1/2-Inch Drive 12-Point Long Hand Socket, 8-36mm Range

Brief Overview

This is a professional-grade extended-length hand socket series designed for the 1/2-inch drive standard. The 12-point (double-hexagon) design provides multiple contact angles with fastener heads, reducing the risk of rounding and allowing engagement from tighter work angles—a critical advantage when working in confined engine bays or machinery assemblies. The extended 77-85mm barrel length allows access to fasteners recessed in deep cavities where standard sockets fall short. Chrome-plated finish resists corrosion, while the knurled midsection band improves grip control during hand-wrench operation.

For mechanics requiring a broader fastener coverage, [6-point long-hand sockets](https://place-holder-link/{ID: 1697}) offer enhanced grip on larger fasteners, while [additional 12-point variants](https://place-holder-link/{ID: 1690}) are available across overlapping size ranges to support fleet standardization.

Key Features

• 12-Point Internal Profile: Multiple engagement angles minimize cam-out and reduce fastener damage on rounded or damaged bolt heads
• Extended Barrel Length: 77-85mm depth reaches fasteners in deep recesses, engine blocks, and confined assembly areas
• Chrome-Plated Finish: Corrosion resistance and professional appearance maintain resale and rental inventory value
• Knurled Grip Band: Textured midsection provides secure hand control without tool slippage
• Precision-Machined Construction: Toleranced drive fit ensures secure seating on 1/2-inch square drive tools
• Comprehensive Size Range: 8mm through 36mm covers standard metric fastener specifications with no critical gaps

Business Advantages for Distributors

• High-Turnover SKUs: Socket sets are core inventory for every professional shop, fleet maintenance operation, and OEM service facility
• Recurring Orders: Mechanics replace worn sockets regularly; extended-length variants address the "missing tool" problem shops encounter
• Margin-Friendly: Hand sockets carry strong wholesale-to-retail margins, particularly when bundled or cross-sold with drive tools
• Fleet/Contract Sales: Maintenance departments standardizing on metric fastener coverage will purchase full ranges to ensure completeness
• Complementary Positioning: Pair with ratchets, breaker bars, and impact tools to increase basket value per order

Application & Suitability

Ideal For:

• Automotive engine and transmission assembly (valve covers, spark plug access, alternator mounts)
• Industrial machinery maintenance (deep cavity fasteners, recessed bolts in compressors, pumps)
• Heavy equipment service (loader buckets, hydraulic cylinders, frame repairs)
• OEM/fleet service where fastener recessing requires extended reach

Not Recommended For:

• Impact-gun applications (use impact-rated sockets instead)
• Torque-critical fastening above hand-wrench force limits
• Open-ended wrench applications (sockets are enclosed tools only)

Why Choose This Range

The 12-point geometry is often misunderstood in the market: it is not stronger than 6-point, but it is more forgiving on damaged fasteners and allows faster engagement angles. Paired with extended barrel length, these sockets solve a specific, high-frequency shop problem—accessing fasteners in cavities where standard-depth sockets cannot reach without tool stacking or adapter chains.

Stock this series as a foundation inventory item for any distributor selling to professional mechanics. The 8-36mm range covers approximately 85% of metric fastener requirements in automotive and industrial service. Rotate inventory regularly; these tools see high shop-floor wear and consistent replacement demand.

Order Strategy Recommendation

• Minimum Order: Full range (20 SKUs) ensures no gaps in mechanic coverage and simplifies inventory management
• Volume Pricing: Consider case-quantity breaks for bulk fleet orders (maintenance departments purchasing for multiple vehicles/machines)
• Cross-Sell Bundling: Pair with 1/2-inch drive ratchets, torque wrenches, or impact wrenches to increase per-order value
