NYLON PATCH NOTES
Fasteners won't work loose:  Resistant to vibration or reversal of stress; locks whether fasteners are seated or unseated, making it ideal for use with gaskets, plastic or glass.
Saves time:  Fasteners can be automatically fed through standard feeding devices.
Saves Money:  Requires no costly lock-washers, cotter pins or castellated nuts.  Greatly reduces or eliminates need for retightening.
Resists heat and cold:  It meets and exceeds (F) Specifications 124 and Military Specifications Mil-F-18240 for temperatures from - 70º to + 250º F.
Resists chemicals:  Will not dry, shrink or lose resiliency when exposed to commercial solvents, alcohol, gasoline, oil, caustic soda, jet fuel, etc.
Reusable:  Fasteners can be re-used repeatedly without damage to threads.  Locking torque will increase 20-25% within 24 hours after installation.
