Koken 1/4Dr 9.0mm Socket Deep

The Koken 2305M09 is a precision-engineered deep 12-point socket designed for use with 1/4" (6.35 mm) square-drive tools. Made in Japan, it features an extended 50 mm length and durable chrome-plated chrome-molybdenum alloy construction, delivering reliable performance for recessed 9 mm metric fasteners. Applications: *Ideal for reaching recessed 9 mm metric fasteners in machinery, automotive assemblies, and equipment housings. *Perfect for professional and DIY use on electronics, appliance repair, and bicycle maintenance where extended reach is required. *The deep 50 mm length streamlines access behind panels or in tight engine bays. *The 12-point configuration provides faster re-engagement and enhanced versatility in high-frequency maintenance tasks. *Flat-drive design minimizes wear on both socket and fastener, increasing tool and fastener longevity.
