Socket

The Koken 3305M10 is a high-precision, deep-reach 12-point socket featuring a 3/8" square drive and a 10 mm hex opening. Made in Japan, it offers full-contact engagement and robust torque delivery. With a 55 mm length, it is perfect for reaching recessed fasteners in automotive, industrial, and maintenance scenarios.

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