DIN 934 Field of Application

This standard specifies requirements for M1 to M160 hexagon nuts. assigned to product grade A (up to size M16) or product grade B (for sizes above M 16). If. in special cases. nuts are to comply with specifications other than those given in this standard, e.g. regarding property class, they shall be selected in accordance with the relevant standards.

Sizes in brackets should be avoided if possible. P= pitch of coarse thread as specified in DIN 13 Part 12. 2) As a deviation from ISO 4759 Part 1. tolerance zone h12 instead of h13 shall apply for widths across flats up to and including 4 mm. Minimum dimensions corresponding to tolerance zone h14 instead ofh13 shall be permissible for M 5 to M 16 hot dip galvanized nuts.

l) Where a protective coating is applied. e.g. an electroplated coating complying with DIN 267 Part 9, depending on the coating thickness requlred. It may be necessary, particularly in the caso of tolerance class OH nuts. to select a larger fundamental deviatlon than that assigned to tha H posltion (800 DIN 267 Part 9). ThiG, impair the (631stance ot the bolt/nut assembly to stripping.
