Socket

The Koken 3305A16 is a precision-engineered, deep-reach 12-point socket featuring a 3/8" square drive and a 1/2" hex opening. Made in Japan, this durable tool offers full-contact engagement and consistent torque delivery. With a 55 mm overall length, it enables access to recessed fasteners in tight spaces for automotive, industrial, and maintenance applications.

Features:
*3/8" square drive for compatibility with standard ratchets.
*12-point (bi-hexagonal) design provides multiple engagement angles for quick fit and high torque capacity.
*Deep-socket length (55 mm) enables access to recessed or hard-to-reach fasteners.
*Full-contact geometry reduces fastener rounding and improves torque transfer.
*Constructed from hardened, chrome-alloy steel, cold-forged and heat-treated for toughness.
*Precision Japanese manufacturing ensures consistent, quality performance.
