ISO 8675:1999 pdf free.Hexagon thin nuts (chamfered) with metric fine pitch thread — Product grades A and B.
Introduction
This International Standard is part of the complete ISO product standard series on external hexagon drive fasteners. The series comprises:
a) hexagon head bolts (ISO 4014 to ISO 4016 and ISO 8765);
b) hexagon head screws (ISO 4017, ISO 4018 and ISO 8676);
c) hexagon nuts (ISO 4032 to ISO 4036, ISO 8673 to ISO 8675);
d) hexagon bolts with flange (ISO 4162 and ISO 15071);
e) hexagon nuts with flange (ISO 4161 and ISO 10663);
f) structural bolts and nuts (ISO 4775, ISO 7411 to ISO 7414 and ISO 7417).
This International Standard specifies the characteristics of hexagon thin nuts (chamfered), with metric fine pitch thread, with nominal thread diameters d from 8 mm up to and including 64 mm, with product grade A for sizes d up to and including 16 mm and product grade B for sizes d over 16 mm.
If, in special cases, specifications other than those listed in this International Standard are required, they should be selected from existing International Standards, for example ISO 724, ISO 898-6, ISO 965-1, ISO 3506-2 and ISO 4759-1.
Coarse thread hexagon nuts according to Iso 4035 should be the first choice.
