Installation Guidelines

  • Use a standard screw gun with a depth-sensitive nose piece and use extra caution when installing with impact drivers. Suggested screw gun specification for optimal performance - Size #8 - #10 up to 2,500 RPM, Size #12 up to 1,800 RPM; however, 2,500 RPM may be used provided care is exercised to minimize influence of high heat buildup due to surface speed (see ASTM C1513, Table 5, note C).
  • The Bugle Head is fully seated when the top of the head is flush with the work surface.
  • The fastener must penetrate beyond the metal a minimum of three full threads.
  • Overdriving my result in fastener failure or strip out of the work surface.
