Specification for bolts and reference standards

Characteristic Standard
Material Steel
General Requirements EN 14399-1
Thread Tolerance 6ga
International Standard ISO 261, ISO 965-2
Mechanical Properties Property Class 10.9
European Standard EN  ISO 898-1
Impact Strength Value Kv, min = 27 J at -20°C
Test Pieceb ISO 148
Test EN 10045-1
Tolerances Product Grade C except: dimensions c and r.   + IT 17
Tolerance for length≥ 155mm:  – 1/2 IT 17
International Standard EN ISO 4759-1
Surface Finishc Self Colour as processed
Hot Dip Galvanised EN ISO 1461
Others to be agreed
Surface discontinuities Limits for surface discontinuities as specified in EN26157-1.
Acceptability For acceptance procedure, see EN ISO 3269.
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.
