High tension hex bolts (M12 – M30) are important products used in constructing steel frame buildings and bridges.

  • A high tension hex bolt special steel containing materials such as low carbon manganese, chromium and boron steel (developed by Old Sumitomo Metal Industries) is used to deliver stable mechanical product characteristics.
  • Product quality consistency is ensured through the use of an integrated manufacturing method driven by new advanced bolt forming equipment (below 27mm diameter).
  • Large diameter high tension hex bolts (M33 – M76) are also manufactured according to time tested hot forging technologies.
  • Strict product lot management (based on JIS B1186) ensures stable quality in high volume manufacturing.
  • Orders for standard products are quickly filled from plentiful stock.
