Maintaining voltage consistency is vitally important for electrical grounding applications in any industry, and REMINC thread-forming and thread-locking fasteners have set the performance benchmark in grounding applications over the years.

In 2020 REMINC contracted Element Materials Technology, an A2LA-certified independent testing lab in Warren, MI to evaluate the electrical grounding performance of TAPTITE PRO® thread-forming fasteners and POWERLOK® II™ mechanical thread-locking fasteners against that of a conventional machine screw. The testing was performed as prescribed by SAE International in their Test Procedure for Electrical Ground Attachment specification also known as SAE / USCAR-26.

The test compared the performance of 20 TAPTITE PRO® thread-forming fasteners in untapped steel weld nuts, 20 POWERLOK® II™ thread-locking fasteners in tapped weld nuts and 18 machine screws in tapped weld nuts (two machine screw sample terminals were damaged during setup and eliminated from the test). All nuts were E-coated, as consistent with common automotive practices.

The results, summarized at right, reveal that TAPTITE PRO® thread-forming fasteners and POWERLOK® II™ mechanical thread-locking fasteners yielded 60% less voltage drop with 80% more consistency than conventional machine screws.

In addition to their exceptional grounding performance, these fasteners also reduce product cost and weight by eliminating parts, processes and associated overhead as well as the energy required to produce, ship, process and install these unneeded solutions.
