Frankford Arsenal 2 lb Stainless Steel Pins
These 2-pound pins measure 1mm by 7mm and are designed for easy magnetic handling to prevent rust. They’re ideal for replacing lost pins or cleaning smaller batches of brass. The pins are particularly reliable for cleaning the interior primer pockets and the case body, making them a solid pick for rotary tumbling systems.
2.5 lb Stainless Steel Pins — FULLBOW
This 2.5-pound batch of stainless steel pins is compatible with Frankford Arsenal tumblers and uses magnetic 304-grade stainless steel. The corrosion-resistant pins serve as effective brass cleaning media, packaged in a sturdy plastic jar for long-term storage. Specifications include a 0.039″ diameter and 0.255″ length, balancing cleaning action with durability.
GANGOU 2.5 lb Stainless Steel Pins
This 2.5-pound magnetic stainless steel media uses 304-grade pins with a 0.039″ diameter and 0.255″ length. It delivers rust and corrosion resistance, making it suitable for repeated polishing cycles while maintaining shape and effectiveness in cleaning primer pockets and case bodies.
Frankford Arsenal 5 lb Stainless Steel Pins
Offering five pounds of pins, this option provides the same magnetic handling and rust resistance as lighter bundles. The pins are sized 1mm x 7mm, making them suitable for larger batches and efficient rotary tumbling that targets interior primer pockets and case bodies for thorough cleaning.
TOAAOT 2.5 lb Stainless Steel Pins
TOAAOT’s 2.5-pound set is compatible with Frankford Arsenal tumblers and most rotary case tumblers. The pins are magnetic and measure 0.039″ in diameter with a 0.255″ length. They are described as effective for cleaning primer pockets and the case body, and they perform well in wet rotary tumbling environments.
Buying Guide: Key Purchase Considerations
When selecting stainless steel media for brass cleaning, several factors influence performance and value. Magnetic handling is essential for easy separation from brass, and 304-grade stainless steel provides corrosion resistance for repeated use. Consider batch size: larger bundles suit high-volume reloaders, while smaller pins are practical for hobbyists working with limited brass. Tumbler compatibility matters; most pins are designed for Frankford Arsenal or other common rotary tumblers, so verify fitment before purchasing. Diameter and length (commonly 0.039″ x 0.255″ in many pins) affect cleaning efficiency and the risk of pin damage to delicate brass.
Durability and rust resistance are critical over long-term use. Magnetic pins simplify removal and reduce wear on equipment. Some kits emphasize mixed shapes or additional media, such as ballcone or disc beads, for broader polishing coverage. For precision cleaning, consider media that targets difficult areas like primer pockets while avoiding excessive abrasion to avoid thinning or deforming case mouths. Finally, storage quality—-packaging that protects from moisture—helps preserve performance over time.
Product-to-product comparisons:
- Size and shape: Most pins are 0.039″ diameter and 0.255″ long, while some kits use 1mm x 7mm pins; both target inside case components effectively.
- Magnetism: All listed options highlight magnetic handling for convenience and rust prevention.
- Batch capacity: 2–3 pounds are common for small-to-medium reloading tasks; 5 pounds supports larger operations.
- Compatibility: Verify tumbler compatibility; most pins work with standard rotary tumblers but confirm model specifics.
By evaluating these considerations, builders can choose media that aligns with their reloading volume, equipment, and maintenance preferences, ensuring efficient brass cleaning and longer tool life.
