• Uncoated carbon steel and the zinc coated fasteners were extensively corroded after 90-day salt spray exposure and the nuts were very difficult to remove.
  
• Teflon and epoxy coated fasteners were corroded at locations of coating damage after 90-day salt spray exposure.
  
• The NUT-SEAL system protected fasteners were free of any corrosion after 90-day salt spray exposure.
  
• Conventional Zn, epoxy and Teflon coatings all exhibited corrosion particularly at sites of coating damage and were less effective than the NUT-SEAL system in protecting the bolts from weight loss corrosion.
  
• The NUT-SEAL nut and thread protector system is effective in mitigating corrosion of bolts in exposure to corrosive H2S-containing atmospheres.
  
• Both corrosion testing and actual field performance have proven the NUT-SEAL system as an effective solution for fastener corrosion in a wide range of applications.
  
• Based on longevity, efficiency and safety, the NUT-SEAL system is less expensive than anything on the market and provides significant time savings by protecting the nut and bolt from corrosion and physical damage, allowing easy removal of the nuts from the bolts and reuse.
  

Both corrosion testing and actual field performance has shown this protector system to be an effective solution for fastener corrosion in a wide range of applications.
