Hexagon regular nuts (style 1). Product grades A and B

Effective date 2017-01-01

1 Scope

This standard specifies the characteristics of hexagon regular nuts (style 1), with threads from M1.6 to M64 inclusive, product grade A for threads D < M16 and product grade B for threads D > M16.

In cases where characteristics differing from those established in this standard are required, they may be selected from current international standards, for example ISO 724, ISO 898-2, ISO 965-1, ISO 3506-2 and ISO 4759-1.

Note — For hexagon high nuts (style 2), see ISO 4033.
