Socket

The Koken 2405A14 is a precision-engineered 12-point socket designed for use with 1/4" (6.35 mm) square-drive tools. Made in Japan, it features a standard 22 mm length and durable chrome-plated construction, delivering reliable performance for medium-duty SAE fasteners.

Features:
*Drive size: 1/4" (6.35 mm) square drive.
*12-point geometry provides twice the engagement angles for faster positioning on nuts and bolts.
*Standard 22 mm length suitable for flush or slightly recessed fasteners.
*Total outer width of approximately 15.5 mm accommodates a 7/16" socket.
*Chrome-plated finish offers corrosion resistance and easy cleaning.
*Flat-drive design ensures full contact between the socket and fastener for optimized torque transfer.
*Forged chrome-molybdenum alloy steel, cold-forged and heat-treated to meet or exceed DIN/ISO strength standards.
