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

Brief Overview

This 1/4-inch drive 12-point long hand socket series delivers precision access to recessed or hard-to-reach fasteners in tight engine bays, panel work, and assembly operations. The extended length and knurled grip band make these sockets indispensable for mechanics who need reliable reach without compromising control. Pair these with 6-point socket alternatives for maximum versatility across your socket range, or stock the complete 12-point long socket collection for comprehensive coverage.

Key Features

• 12-Point Double-Hex Profile: Engages fastener corners for secure grip, reducing rounding on worn or softer fasteners
• Extended Length Design: 50mm overall length reaches recessed bolt heads and fasteners in confined spaces
• Knurled Grip Band: Central machined knurling ensures confident hand grip without slipping, even under wet or oily conditions
• Satin Chrome Finish: Durable, corrosion-resistant surface maintains appearance and resists oxidation during heavy use
• Precise Machining: Tight tolerances on drive recess and socket profile ensure perfect fit with ratchets and drivers
• 14-Size Range: 4mm through 14mm coverage addresses most precision fastener applications in automotive and industrial work

Business Advantages for Resellers

• High-Margin Consumable Alternative: While not consumable themselves, these sockets drive repeat purchases as mechanics build complete socket sets across multiple shops and vehicles
• Essential Inventory Item: Every professional mechanic requires long sockets; stocking all 14 sizes positions you as a one-stop supplier
• Bulk Order Potential: Mechanics typically purchase complete sets or multi-unit quantities for shop inventory and personal tool kits
• Competitive Pricing Structure: White-label positioning allows you to offer superior margins compared to branded alternatives
• Low Return Rate: Precision machining and chrome finish minimize defects and warranty claims

Why Choose This Series

The 12-point geometry provides a critical advantage over 6-point sockets when working with damaged or worn fastener heads—the additional contact points distribute load more evenly and reduce cam-out risk. The extended 50mm length addresses the specific challenge of accessing fasteners recessed behind panels, in tight engine compartments, or on assembly fixtures where standard sockets simply won't reach.

The satin chrome finish resists corrosion and maintains professional appearance across hundreds of applications. Machined knurling in the grip band—a feature absent from cheaper alternatives—prevents hand slippage during critical fastening operations, directly improving shop safety and efficiency.

Reseller Recommendation

Stock the complete 14-piece set to capture the full margin on mechanics building or upgrading their tool kits. The proven demand for precision sockets in this size range, combined with low defect rates and minimal returns, makes this an essential inventory rotation item that supports consistent monthly turnover.
