The ServoCity Plastic Servo Hub (H25T Spline, 32mm Diameter) is designed to facilitate the connection of goBILDA® components to a 25 tooth servo. It accommodates 16mm pattern components, including gears, sprockets, and pulleys, through four thru-holes for M4 thread-forming screws. Additionally, it features slots for conventional machine screws with M4 nuts in hex counterbores, allowing for the attachment of linear parts such as beams with 24mm spacing across slots.
