Why This Socket Works

The 12-point profile is engineered for precision fastener work—ideal for recessed bolts on engines, transmissions, and electrical assemblies where a 6-point socket cannot reach or secure the fastener. The long body minimizes wobble in deep cavities, and the consistent 63mm length across all sizes simplifies inventory management. The knurled grip ensures mechanic comfort during repeated use, reducing hand fatigue on high-volume jobs.

Call to Action
