We also carry an enormous inventory of teflon nuts which some refer to as PTFE 2H NutsTeflon blue coated nuts are also very commonly used in the industry as fluropolymer coated fasteners allow for an excellent resistance to corrosion while promising an easy on/easy off assembly.  Xylan, Teflon, and Fluorocote #1 are all brand name PTFE coatings that we either stock readily made or have the capability of coating at our in-house ptfe coating line specifically designed for fasteners.  The increased lubricity, and the ability to remove nuts easily is a large safety factor for the fact hot-work permits don’t have to be given to cut away a rusted nut/bolt.
