  • Weatherproof fastener because the splined stem plugs the entire length of the shell.
  • High shear and tensile strength.
  • All stainless steel option for high corrosion resistance and applications requiring elevated temperatures.
  • Interference lock formed by a splined stem
  • Spreads the tail bearing/clamp load on the rear sheet
