1 Refer to Figure in Section 3.6.1.5.
2 For coating abbreviations, Zinc-1 = ASTM F1941; BP = Black Phosphate. For more information on corrosion resistance, reference Section 3.6.1.6.
Warning:
Because of the potential for delayed hydrogen assisted stress corrosion cracking, many hardened steel fasteners
are not recommended for use with dissimilar metals or chemically treated wood when moisture may be present or in corrosive
environments. For further information, contact Hilti Technical Support at 1-877-749-6337.
