Koken Drive Universal Double Joint Z-Series Socket

The Koken Z-Series Universal Double Joint (also called a double-joint universal socket adapter or flex joint) lets you turn fasteners at an angle. It is made for tight spots where a straight socket and extension can't fit. Koken builds the Z-Series for low-profile work in hard-to-reach places.

Key Features:

• Dual ball-joint design: two joints give smooth, fluid rotation through a wide combined swing angle.
• Load-sharing connection: the joints link through interlocking hexahedron-shaped surfaces. This spreads the load around the whole outer circumference of the tool.
• Compact Z-Series (Z-EAL) profile: the low-profile body is made for confined spaces.
• Close tolerances: a snug, precise fit on the drive tool and fastener.
• Square drive: works with standard ratchets, breaker bars and extensions in the matching drive size.
• Made in Japan: Koken has made socket wrenches for about half a century.

Use it for spark plugs, hidden fasteners and other jobs where access is limited. Mechanics, technicians and serious DIYers who want a dependable, precisely made tool will find it useful.
