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.

Important Note

Preloaded bolted assemblies are very sensitive to differences in manufacture and lubrication. Therefore it is important that the assembly is supplied by one manufacturer who is always responsible for the function of the assembly. For the same reason, it is important that the coating of the assembly is under the control of one manufacturer. Beside the mechanical properties of the components, the functionality of the assembly requires that the specific preload can be achieved if the assembly is tightened with a suitable procedure. For this purpose a test method for the suitability of the components for preloading was created, which will demonstrate whether the function of the assembly is fulfilled.

Specification for bolts and reference standards

Characteristic							Standard
Material							Steel
General Requirements							As specified in DIN 267 Part 1.
Thread			Tolerance				5g6g for property class 12.9; 6ga for other property classes.
			Standard				ISO 261, ISO 965.
Mechanical Properties			Property Class (material)				d ≤ M39b: 8.8; 10.9; 12.9 d > M39: as agreed
			Standard				DIN ISO 898 Part 1
Tolerances on dimensions and form			Product Grade				A
			Standard				ISO 4759/1/DIN ISO 4759 Part 1
Surface finish							Black oxide (thermal or chemical)
							DIN 267 Part 2 shall apply with regard to surface roughness.
							DIN 267 Part 19 shall apply with regard to the permissable surface defects.
							DIN 267 Part 9 shall apply with regard to electroplating.
							If different electroplating or other surface protection is desired, this shall be agreed upn at the time of ordering
Acceptable inspection							DIN 267 Part 5 shall apply with regard to acceptance testing.
a   Only for screws without surface protection, 6g makes it possible for normal coating thicknesses to be applied in accordance with DIN 267 Part 9 but the reference line shall not be exceeded. Depending on the coating thickness required, a larger fundamental deviation shall be selected that for the g position. A larger fundamental deviation may impair the stripping strength of the screw/nut connection. b  In ISO 4762, only up to M36 or below.
