Hex Flanged Head SDS (Epoxy)

Hex Flanged Head SDS (Epoxy)

Features :
  • Unique Coating Advantages : Epoxy Polymer Coating is a water based Coating
  • Base Metal is covered with electro-zinc plating which is then covered with epoxy based organic polymer through electro-Coating process.
  • Ploymer coating acts as an anti-corrosive agent in humid environment wherein electro-zinc plating plays the role of sacrificial element
  • Zinc corrodes due to chemical reaction thrus protecting the base from getting rusted
  • Coating process is in accordance with AS3566 Class 3
  • Minimum thickness of coating is 25microns
  • Made from Ultra tough carbon steel C-1022
  • Cold Forged & heat treated for extra strength & durability
  • Unique Drill Point to maximize performance with minimum efforts
  • Sharp thread threads design maximize pull out and minimise backout
Applications :
  • For Humid to very humid environment
  • Ideal for Green building strructures
  • Medium to heavyt purpose
  • Stitching roof decks and wall panels
  • Residential, commercial and industrial frame construction
Technical Details :
  • Material : C-1022
  • Case Hardened
  • Coating: Epoxy
  • Finish : Dark Grey/Green
  • Washer : EPDM
