3/8-Inch Drive 12-Point Long Hand Socket

Overview

This 12-point long hand socket delivers the precision and reach your technicians need for deep-access fastener removal and installation. Engineered for 3/8-inch drive systems, the extended 63mm shaft length provides superior clearance in confined spaces—ideal for suspension work, engine bay access, and assembly operations where standard sockets fall short. The 12-point profile grips fastener flats securely, minimizing cam-out and fastener damage on precision components. Whether you're stocking individual sizes or building a complete long-reach socket range, these sockets deliver consistent performance across automotive, industrial, and maintenance applications.

Key Features

• 12-Point Internal Profile – Grips hex fasteners with dual-contact geometry, reducing rounding risk on damaged or soft fasteners
• Extended 63mm Length – Reaches fasteners in recessed mounting points, suspension components, and engine bay restrictions

Why This Socket Works

The 12-point design is your advantage when fasteners are tight, corroded, or partially rounded. Unlike 6-point sockets that contact only three flats per rotation, the 12-point geometry distributes load across six contact points, dramatically reducing fastener damage during removal. The extended shaft reaches into suspension turrets, engine block mounting points, and recessed bolt holes where standard sockets simply cannot reach—this is not a universal tool, but a specialist's tool for the jobs that demand it.

The consistent 63mm length across all sizes simplifies your inventory: your technicians know exactly what they're getting regardless of fastener diameter. The knurled grip ring provides tactile feedback and control during hand operation—important when working in tight quarters where feel matters as much as precision.

Stocking Strategy

Build your inventory around your market demand. Common fastener sizes (10mm, 13mm, 15mm, 17mm, 19mm) move fastest in automotive work. Consider stocking these heavily and offering others as special order to optimize your working capital. The 8–24mm range covers approximately 95% of automotive fastener applications, making this a core product for any professional shop.
