| a The tolerance class specified applies before hot-dip galvanising. Hot-dip galvanised bolts are intended for assembly with oversize tapped nuts. b The location of chappy V-notch test pieces in the bolt shall be specified in EN ISO 898-1. c Attention is drawn to the need to consider the risk of hydrogen embrittlement in the case of bolts of property class 10.9, when selecting an appropriate surface treatment process (e.g. cleaning and coating), see the relevant coating standards. d “As processed” means the normal finish resulting from manufacture with a light coating of oil. e Other coatings may be negotiated between the purchaser and the manufacturer provided they do not impair the mechanical properties or the functional characteristics. Coatings of cadmium or cadmium alloy are not permitted. |
