DURA-CON® CORROSION RESISTANT FASTENERS

WHY DURA-CON® CORROSION RESISTANT FASTENERS?
DURA-CON® Corrosion Resistant Fasteners are the only fastener specifically tested for use in solar racking materials.


WHAT KIND OF TESTING HAS BEEN DONE?
For a side-by-side corrosion resistance test, DURA-CON® Corrosion Resistant Fasteners and 18-8 stainless steel fasteners were installed in 6063 and 6105 aluminum material and exposed to 1500 hours of Salt Spray Testing in accordance with ASTM B-117 and Torque-Tension Tests have been done with DURA-CON® Corrosion Resistant Fasteners to compare with stainless steel fasteners the range of torque values required to achieve desired clamp load (tension) in a fastened joint.

HOW DID DURA-CON® PERFORM?
At the end of the Salt Spray Testing, both the DURA-CON® Corrosion Resistant Fasteners and the stainless steel fasteners showed equal resistance to Environmental Corrosion.  When the fasteners were removed from the aluminum, there was no sign of Galvanic Corrosion in the DURA-CON® Corrosion Resistant Fasteners assembly but the stainless steel assembly showed signs of Galvanic Corrosion as the aluminum was beginning to corrode.

The Torque-Tension Tests showed that DURA-CON® Corrosion Resistant Fasteners achieved desired clamp load within a much narrower range of torque values than the stainless steel fasteners.

WHAT DO THESE TEST RESULTS MEAN TO ME?
Three things:
  1. DURA-CON® Corrosion Resistant Fasteners are an upgrade from galvanized with resistance to environmental corrosion.
  2. DURA-CON® Corrosion Resistant Fasteners actually surpass stainless steel in galvanic corrosion situations when using aluminum materials.
  3. Predictable driving torque means consistent tightening during assembly with less loss of clamp load during service.  The joint stays tight.
ARE THERE ANY OTHER REASONS TO CONSIDER DURA-CON® CORROSION RESISTANT FASTENERS?
Yes!  The problem of thread-galling is eliminated.  If you have experienced this problem you know how frustrating it can be to have a nut “seize up” while being tightened onto a bolt.


WHAT DO DURA-CON® CORROSION RESISTANT FASTENERS COST?
In most cases, DURA-CON® Corrosion Resistant Fasteners can save money when compared to stainless steel.  DURA-CON® Corrosion Resistant Fasteners are produced to order for use in high production situations.  In those cases savings can be as high as 40% but typically run in the 25%-30% range.  The lower price plus improved performance during the assembly process (no galling, etc.) means substantial savings with increased productivity.
