Die Ring 420 Stainless Steel by Derraco
Premium lock ring for all standard reloading dies
The Die Ring 420 Stainless Steel from Derraco Engineering is a universal lock ring that fits all standard 7/8-14 reloading dies. This high-quality ring combines the durability of stainless steel with a well-designed split design for optimal performance and long lifespan.
CNC-manufactured from 420 stainless steel
Unlike the aluminum lock rings that come standard with many dies, this ring is fully CNC-turned and milled from 420 stainless steel. This material offers superior hardness and corrosion resistance, meaning the ring will not rust or deform, even after years of intensive use. The precision CNC machining ensures all surfaces are perfectly flat and parallel.
Split design with improved grip
The split ring design offers several advantages over solid ring constructions. The split in the ring provides more uniform distribution of clamping force around the entire diameter of the die. This prevents concentration points where tension could build up and results in a more reliable lock that does not shift during use.
Universal compatibility
This die ring fits all standard 7/8-14 thread dies, which is the industry standard for reloading dies. Whether you use Redding, RCBS, Hornady, Lee, Forster, Whidden or another brand of dies, this lock ring is fully compatible. This makes it an ideal upgrade for your entire die collection.
No damage to die threads
An important advantage of the split ring design is that no set screw presses directly into your die's threads. Traditional lock rings with a set screw can cause small dents or damage in the threads with repeated use. This split design completely eliminates that risk, which is especially important with expensive premium dies.
Resistant to chemicals and wear
The 420 stainless steel is not only corrosion-resistant but also resistant to the various chemicals you encounter during reloading, such as case lube, sizing wax and cleaning agents. Moreover, the material is hard enough to resist wear, even with frequent die changes.
Practical advantages
This die ring offers several practical advantages for the reloader:
- Easy to tighten without special tools
- Maintains its shape with repeated tightening and loosening
- Does not rust during long-term storage
- Suitable for both single stage and progressive presses
- Maintains accurate die height setting
- No maintenance required
Ideal for multiple applications
This universal lock ring is suitable for all types of reloading dies:
- Full length sizing dies
- Neck sizing dies
- Bullet seating dies
- Crimping dies
- Body dies
- Powder through expanding dies
- Universal decapping dies
Upgrade for existing dies
For reloaders looking to upgrade their setup, this stainless steel lock ring offers a cost-effective way to improve the performance and durability of existing dies. Instead of purchasing completely new dies, you can equip your current dies with these premium lock rings.

Installation and use
Using this lock ring is simple and intuitive. Screw the ring onto your die, place the die in your press and set the desired height. Then tighten the ring finger-tight. Due to the split design, you don't need to tighten extremely hard, the ring clamps itself firmly. When loosening, minimal force is needed, which speeds up die changes.
Comparison with other materials
While aluminum lock rings function fine for casual use, stainless steel offers clear advantages for serious reloaders. Aluminum is softer and can deform with repeated tight tightening. It can also oxidize and discolor. Stainless steel maintains its shape and appearance much better over time, resulting in more consistent performance and a more professional appearance of your reloading setup.
