7/8 x 14 UNF thread — Industry-standard threading fits most major die brands including Lee, RCBS, Redding, Lyman, Forster, and Simplex. (Note: Not compatible with Super Simplex, which uses 5/8" thread.)
1.378" / 35 mm outer diameter — Measures across the top face of the ring. Use this figure to assess turret press spacing requirements or potential interference with adjacent dies.
Fit and finish verified during quality control — Each ring is checked against actual reloading dies during manufacturing to ensure proper clearance, smooth threading, and consistent locking pressure prior to packaging.
Black Type II anodized coating — Creates a non-porous, wear-resistant surface that resists abrasion, oxidation, and chemical corrosion. Precision finish that holds up to high-volume reloading and repeated tool handling
Note: Consider polishing the tip of your C-spanner and/or coating it with liquid electrical tape to minimise marring on anodised or plated finishes.
3PCS in a pack — Most reloading setups use three dies: a full-length sizing die, a bullet seating die, and often an expander or crimp die depending on calibre and loading method.
8 mm thick for structural integrity — Engineered to resist flex under axial load from repeated full-length sizing, case forming, and primer pocket reaming, where conventional rings may shift, deform, or loosen over time.
Cross-bolt design for even clamping force — Applies uniform compression around the die body, unlike grub screw types that create uneven pressure. Secures dies without distortion, rotation, or damage to threads. 🔧 Includes Allen wrench — Convenient for immediate setup and adjustment without hunting for tools.
C-spanner slots for equal torque removal — Prevents loss of die zero when breaking torque under buildup from condensation, residue, or carbon. Ensures smooth, even removal without tilting, binding, or damaging thread faces.
