These Sinclair Die Lock Rings are machined from stainless steel and fit all standard 7/8 thru 14 reloading dies or press mounted accessories. The lock ring surfaces are machined flat and parallel, and the cross bolt design with no lock screw contacting the die threads is preferred by most experienced reloaders. We incorpated a larger hex screw crossbolt (seven by sixty fourth inch hex wrench) but designed the crossbolt recess so the hex head does not protrude from the lock ring circumference. Available singly or at a discount in 3-packs. Will fit Forster CO-AX Press.
