It means the nails have a standard steel finish without any protective coating like zinc plating or galvanization. They are shiny upon manufacturing but can oxidize (rust) if exposed to moisture.

The inset rings on the shaft create a stronger grip within the material, significantly reducing the chance of the nail backing out over time compared to smooth-shank nails.

Check your nailer's specifications for compatible nail diameter (2.5mm) and maximum length (64mm), and ensure it accepts flat-collated nails.

Check the air pressure setting on your compressor; increase if too low. Ensure the nailer is set to the correct depth. Verify the nails are loaded correctly and the magazine is free of debris.

Confirm the nail diameter and length are correct for your tool. Check that the tool is suitable for the density of the material being fastened. Ensure sufficient air pressure is supplied to the tool.
