Big head screw shank nails

Trurnit-big head screw shank nails
and wheel head
Big head screw shank nails are constructed similarly to big head nails with smooth shank but possess a wooden screw thread which more than doubles the extraction values (PDF).
The large head plate (d = approx. 20 mm) makes these nails particularly suitable for fastening soft and/or porous materials, such as lightweight boards, mesh, pressboards, roofing and wall insulation boards, plastic foams etc. through which a smaller nail head would sink.
Big head screw shank nails are not suitable for machine processing.
