1 Scope This standard specifies a selection of tolerances for bolts, screws, studs and nuts with product grades A, B and C and for tapping screws with product grade A. Note: The product grades refer to the size of the tolerances where grade A is the most precise and grade C is the least precise. The tolerances, except tolerances for threads, are selected from GB/T 1800.2 and GB/T 1800.4. The tolerances for metric threads are taken from GB/T 2516. The tolerances for tapping screw threads are covered in GB/T 5280. The tolerances of form and position shall be specified and indicated in accordance with GB/T 1182, GB/T 4249 and GB/T 16671. The tolerances specified in this standard apply to fasteners prior to coating unless otherwise specified. See also GB/T 5267.1. In cases where there is a difference between the tolerance requirements in this standard and the product standard, the product standard shall take precedence It is recommended that these tolerances also be used for non-standard fasteners. Dimensions and tolerances given in this standard are in millimetres. 2 Normative references The following standards contain provisions which, through reference in this standard, constitute provisions of this standard. At time of publication, the editions indicated were valid. All the standards will be modified, however, parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.
