Info
  • A zinc flake coating eliminates the risk of hydrogen embrittlement.
    • All thread lengths are guide values only and may deviate.
    • Due to the unfavourable head geometry these fasteners have reduced loadability.
    • Steel fasteners with reduced loadability are marked with a '0' preceding the property class mark, e.g. '010.9'.
    • Stainless steel fasteners with reduced loadability are either marked with a '0' preceding the property class mark, e.g. 'A2-070', or with the steel grade only, e.g. 'A2'.
