A spool for a fishing reel made of engineering polymer and fitted on a shaft for rotation. The shaft may include a number of peripheral protrusions therearound to present a greater linear surface of contact to assure a bonding of the polymer and shaft to withstand lateral line pressure and to aid in reducing the shrinkage of the polymer during drying in the molding process or other locking means may be employed to prevent movement.
