Fork ends

Threaded fork ends are used to terminate bars and transfer load to the structure. Fork ends are cast components from M12 - M100 (dependent on material). The forks are threaded left hand or right hand depending on the tie rod arrangement and are generally tapped with a blind hole for corrosion detailing.
