Each multi-pack contains several rings (see details below) and a die wrench. All multi-packs feature a black nitride finish. The wrenches are made of aluminum and have a black hardcoat anodized finish. The 7/8 inches multi-pack comprises four rings, each measuring 7/8-14 and includes a wrench The cumulative thickness of the rings measures precisely 1/2 inches Enhanced thread engagement - the rings offer 0.350 inches of thread engagement, providing a 15-25% increase over standard die lock rings for improved stability and performance Internal wrench engagement - traditional rings feature a flat surface or knurling on the exterior, necessitating the use of a wrench around the outside for tightening Precision stainless steel manufacturing - the threads and base of the ring are CNC-machined in a unified process, ensuring orthogonal surfaces for precise die alignment Large diameter - the increased surface contact with the turret head ensures that the ring aligns with the press, thereby directing the die straight This prevents the die from being gripped and aligned in an unintended manner
