DIN 933 vs ISO 4017 specification standard

Date:Jun 06, 2019


DIN 933 is HEXAGON SCREWS; THREAD APPROXIMATELY TO HEAD, METRIC

ISO 4017 is Fasteners — Hexagon head screws — Product grades A and B

ISO_4027_DIN_933_dimensions_chart_specification

DIN 933 and ISO 4017 is interchangeable to each other, the same to hexagon head screw, dimensions, specifications, material, torque etc.



ISO 4017 International Standard specifies the characteristics of hexagon head screws with threads from M1,6 up to and including M64, of product grade A for threads M1,6 to M24 and nominal lengths up to and including 10 d or 150 mm, whichever is the shorter, and product grade B for threads over M24 or nominal lengths over 10 d or 150 mm, whichever is the shorter.


NOTE This type of product is the same as that covered by ISO 4014 with the exception of threading up to head and nominal lengths up to and including 200 mm as preferred lengths.


If, in special cases, specifications other than those listed in this International Standard are required, they can be selected from existing International Standards, for example ISO 724, ISO 888, ISO 898-1, ISO 965-1, ISO 3506-1, ISO 4753 and ISO 4759-1.
