Ko-ken 12-point (12PT) deep sockets are premium, Japanese-manufactured hand and impact tools featuring a flat-drive system to reduce fastener wear and transmit higher torque.
Key Features
Design: 12-point (bi-hexagonal) configuration for double the starting points of a 6-point socket, making them faster and easier to engage on nuts and bolts in tight spaces.
Flat Drive System: Contacts the flat sides of fasteners rather than the corners, preventing rounding.
Material: Cold-forged, heat-treated chrome-molybdenum or chrome vanadium alloy meeting strict DIN and ISO standards.
Origin: Made in Japan.
