RCBS 09604 Lock Ring 1/4-28 Thread - Reloading Die Accessory

The RCBS 09604 Lock Ring provides secure die positioning with its precision 1/4-28 thread specification. This essential reloading component eliminates die movement during operation, ensuring consistent ammunition production and maintaining proper headspace measurements.

What Makes This Different

Unlike standard lock rings that can slip under pressure, the RCBS 09604 features hardened steel construction with precise machining tolerances. The 1/4-28 thread pitch matches RCBS reloading dies perfectly, creating a tight mechanical connection that withstands the forces generated during case sizing and bullet seating operations. Internal threading maintains dimensional accuracy even after thousands of loading cycles.

Key Features

• Precision 1/4-28 thread specification for exact RCBS die compatibility
• Hardened steel construction resists wear and thread damage
• Knurled exterior surface provides secure grip during adjustment
• Heat-treated finish prevents corrosion and maintains thread integrity
• Standard height design fits all RCBS single-stage and progressive presses
• Chamfered edges prevent binding during installation and removal
• Factory-tested threading ensures proper die lockup without overtightening

Reloaders depend on consistent die positioning for ammunition accuracy and safety. This lock ring maintains die height settings between reloading sessions, eliminating the need for constant readjustment. The secure mechanical connection prevents dies from backing out during high-pressure operations like full-length case sizing or crimping heavy bullets.
