Note:

The Nuts will generally conform to ANSI B18.2.4.6M - Metric Heavy Hexagonal Nuts. Thread will conform to Class 6H of ANSI B1.13M for Coarse Series.

Material and Head Treatment:

To achieve mechanical properties of Property Class 8S or 10S of ASTM A 563M

Nuts of property Class 8S are used with bolts of ASTM A325M - Type 1 and 2 (con-coated) Nuts of Property 10S are used with bolts of ASTM A325M - Type1 and 2 (Zinc Coated) In Bolt/Nut assembly, tightening should be done by rotation of Nut. Sizes in brackets are non-preferred standards. All dimensions are in millimeters.
