Socket

The Koken 2405A18 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 length design (24 mm) and chrome-plated construction, delivering reliable performance for 9/16" SAE fasteners.

Features:
*Drive size: 1/4" (6.35 mm) square drive.
*12-point geometry provides twice the engagement angles for quick positioning on nuts and bolts.
*Standard 24 mm length suitable for flush or slightly recessed fasteners.
*Outer width of approximately 19.3 mm to accommodate 9/16" fasteners.
*Inner width (D2) 17.9 mm and depth (H) 11 mm for sturdy fit.
*Chrome-plated finish offers corrosion resistance and easy cleaning.
*Forged chrome-molybdenum alloy steel construction ensures durability and long service life.
*Designed to DIN/ISO strength standards for reliable torque performance.
