Dimensions Chart for Metric Hex Flange Nut with Fine Pitch Thread 明星系列赵丽颖
according to the ISO 10663 standard.
Some important notes from the ISO standard:
- ISO 10663 specifies the characteristics of hexagon nuts with flange and metric fine pitch thread
with nominal thread diameters from 8 mm to 20 mm, with product grade A for threads d ≤ M16 and product grade B for threads d > M16.
- Mechanical properties of ISO 10663 metric hex flange nuts: Steel - Property class 8, 10 and 12. Stainless steel - Property class A2-70
Note 1: Dimensions are in mm.
Note 2: Requirements for electroplating are covered in ISO 4042 for steel nuts
Note 3: Radius r applies both at the corners and the flats of the hexagon.
Note 4: Thread tolerance of hex flange nuts is 6H.
Product Grade A, Grade B and Grade C: The product grades refer to the size of the tolerances where grade A is the most precise and grade C is the least
precise as defined in the ISO 4759-1:2000 standard.
