IFH™ self clinching studs allow for maximum material flow into the stud undercut to create a water-tight seal. Tighter tolerances and process controls produce a consistent reliable ingress capable result every time.
  • Meets ISO:20653-2014 ingress protection levels
  • Ingress repellent capability, meeting IPX7 and IPX9K IP ratings
  • No rubber gasket or sealants needed
  • Testing completed in CR4 steel, 6082-T6 aluminum, and 304 stainless steel
