Buying Guide: Key Considerations For Stainless Steel Pins
How to choose the right pin size and alloy
Pin diameter and length affect cleaning aggressiveness and compatibility with tumblers. 0.039″ diameter pins are common for standard brass cleaning, while 0.047″ pins offer stronger agitation. Stainless steel 304 is corrosion resistant and widely used, while additional alloys may provide specific benefits.
Magnetic handling and batch size
Magnetic pins simplify handling and pin separation. For large batches, choose pins with robust magnetization and compatible tumblers to avoid jams or uneven cleaning.
Compatibility with tumblers
Verify that the pins fit your tumbler model (e.g., Frankford Arsenal tumblers) and that the media quantity aligns with your typical batch size.
Maintenance and longevity
Stainless steel pins resist rust when kept dry between uses. Store pins in a dry container to extend their life and prevent surface corrosion from moisture exposure.
Safety and cleaning outcomes
Proper media selection supports effective brass cleaning without damaging case mouths or primer pockets. Avoid pins that are too large for your case dimensions or too aggressive for delicate brass.
FAQ
- Q: Are stainless steel pins safe for primer pockets?
A: When used as directed, pins can help clean interior brass areas, including some primer pocket surfaces, but avoid aggressive tumbling that may deform pockets. - Q: Which pin size is best for standard brass cleaning?
A: Pins around 0.039″ diameter and 0.255″ length are common and widely compatible with many tumblers. - Q: Do magnetic pins rust if exposed to moisture?
A: Stainless steel pins are corrosion resistant, but store them dry to prevent surface staining and maintain magnet efficiency. - Q: Can I mix brands in a single tumbler load?
A: Mixing pins is generally acceptable if sizes are consistent with the tumbler’s design; improper mixing can affect cleaning balance. - Q: What is the advantage of higher-purity pins?
- A: Higher-purity pins, such as premium German-made options, may offer tighter tolerances and more uniform finishes, aiding consistent cleaning.
