The Forster Products DIEG10 is a Cross Bolt Die Lock Ring that provides superior precision and durability. This unique piece firmly embraces the full circumference of the die. This innovative design ensures increased accuracy in aligning the lock ring threads with the die threads compared to traditional models. This exceptional product is included with all of Forster\'s high-end Bench Rest Dies.The user-friendly cross bolt links both ends of the ring, superseding the conventional screw design that fastens directly into the die\'s threads. By doing so, it enhances the accuracy of the lock ring threads coupling with the die threads. This provides a consistent, reliable alignment, preventing any tilting and consequently, averting any damage to the die threads.They remain undisturbed and in their original condition. All it takes to tighten or loosen the robust steel cross bolt screw is a 7/64 hex key (Allen wrench). This product is versatile and compatible with standard 7/8-14 thread dies from numerous manufacturers.
