1/4-Inch Drive 12-Point Long Hand Socket
Brief Overview
This extended-length 1/4-inch drive hand socket is engineered for precision work in tight spaces and situations where standard socket depth proves insufficient. The 12-point internal geometry distributes load evenly across fastener flats, reducing cam-out and preventing rounding on stubborn or corroded fasteners. With 11 individual sizes spanning 4mm to 14mm, this range covers the majority of metric fastening requirements in electronics assembly, precision automotive work, and light mechanical maintenance. For complementary coverage across drive sizes, consider pairing these with 12-point sockets in larger 3/8-inch drive for heavier applications.
Key Features
- 12-Point Internal Drive: Reduces contact pressure per fastener flat compared to 6-point designs, minimizing wear and rounding
- Extended Barrel Design: 50mm length (except 9mm-14mm variants at 50-60mm effective) provides reach into recessed or hard-to-access fastening points
- Knurled Grip Shoulder: Machined knurling on the barrel collar improves control during manual operation, reducing hand fatigue
- Chrome Satin Finish: Corrosion-resistant surface maintains appearance and performance through repeated use
- Precision Machining: Close tolerances on drive interfaces ensure secure engagement with 1/4-inch square drive tools

Why Professionals Choose This Socket
The 12-point design is not a gimmick—it's a functional advantage. On worn or difficult fasteners, the additional contact points prevent the sliding failure that frustrates mechanics using 6-point designs. The extended length eliminates the need for extension bars in confined spaces, keeping socket assemblies compact and reducing vibration. For inspection work, maintenance, and precision assembly where speed is secondary to accuracy and fastener preservation, this tool earns its place in a professional drawer.
