Koken Universal Joint 3/8Dr

The Koken 3770 is a premium universal (swivel) joint designed for use with 3/8" square drive tools. Made in Japan and measuring 50 mm long, it is built to tackle tight, awkward angles by allowing a 90° swivel between the ratchet and socket. Applications: *Ideal for accessing bolts and nuts in tight or overhung areas where straight alignment isn't possible. *Perfect for automotive repairs, such as under dashboards, engine bays, and transmission work. *Useful in industrial maintenance for reaching recessed fasteners in machinery and equipment. *Also great for plumbing, HVAC, and appliance repairs where angle flexibility is needed. *Enhances tool versatility by enabling more ergonomic hand and tool positioning in constrained spaces.
