An inexpensive riveted joint, designed for low torque ... manual, intermittent or light duty. Unique center block is produced from our own proprietary powdered metal formulation and sintering process. All other components are machined from carbon steel. With its own self-contained oil supply, the block not only acts as a carrying member for the cross-pins, but also as a continuous lubricated bearing block. As a result, the Wakefield-Vette Hex Block Joint lasts longer than other comparable units and is ideal for applications where oiling is required but impractical because of the universal joint location. Maximum operating angle on standard models is 35°. Hex Block Joints can be special ordered for greater angles and other characteristics.
