Socket

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.

Features:
*Drive size: 1/4" (6.35 mm) square drive.
*12-point (double-hex) geometry offers twice the engagement angles of a 6-point socket for faster positioning.
*Deep 50 mm length reaches fasteners recessed behind panels or within assemblies.
*Flat-drive design ensures full contact with fasteners, reducing wear and improving torque transmission.
*Chrome-plated finish protects against corrosion and provides a smooth, easy-to-clean surface.
*Constructed from forged chrome-molybdenum alloy steel, cold-forged and heat-treated to meet or exceed DIN and ISO standards.
