	The Southern Style features the unique Automatic Helix Adjustment. The Helix path of the thread along the line of adjustment remains true in alignment throughout the entire life of the gage. The conventional AGD Style presents a mis-alignment of the threads at the adjusting slot when reset. The Southern Style sets round and stays round through all adjustments, due to the eccentric design and opposing pressures of the adjusting and locking mechanisms. The AGD Style hinges at the two terminal holes and becomes more and more egg-shpaed as the ring is adjusted. The Southern Style Adjusting Screw contacts the conical seat of the insert, maintaining a rigid setting and holding the two thread ends in perfect alignment even through rough handling. The AGD Style sleeve assembly permits the gage faces to become mis-aligned at the adjusting slot.
