① The tolerance class specified applies before electroplating or hot-dip galvanizing. Hot-dip galvanized bolts may also be supplied by agreement between the user and the manufacturer, having screw threads which after galvanizing shall be accepted by a GO gauge of the basic thread size, i.e. the bolt threads are undersized before galvanizing to tolerance class 6az to accommodate the zinc coating. These bolts are designated and marked 8.8S U or 10.9S U ( see also clauses 6 and 7 ). Tolerance class 6az is in the course of preparation, but in the interim the screw thread dimensions are given in annex A. ② Black oxide means the normal finish resulting from manufacture with a light coating of oil. ③ Other coatings may be negotiated between the purchaser and the manufacturer provided they do not impair the mechanical properties. ④ This will be the subject of a future International Standard. ⑤ Precautions to avoid hydrogen embrittlement may be necessary. Reference should be made to the future International Standard dealing with electroplating of threaded components. ⑥ Precautions to avoid hydrogen embrittlement may be necessary.
