Stainless Steel T-Nuts

Stainless steel tnuts are not available in Australia from a reliable source at a reasonable price, so I do not stock them.  I recommend using steel tnuts, and before you install them, place them in a plastic bag and treat them with a long lasting lubricant like CRC Long Life.  Spray them in the bag and shake them around and make sure they are well coated, but not dripping.  Check them occasionally for rust and spot treat them as needed.
