Product Description

Applications

ASTM A563M Heavy Hex Nut specification covers chemical and mechanical requirements
for eight property classes of hex and hex-flange carbon and alloy steel.

These nuts for general structural and mechanical uses on bolts, studs, and other
externally threaded parts.

Astm A563M Materials shall be tested and the individual grades shall conform to specified
values of material such as hardness and proof load, chemical, and mechanical requirements.
Classes 8S, 8S3 and 10S, 10S3 nuts have atmospheric corrosion resistance and weathering
characteristics comparable to those of the steels. The atmospheric corrosion resistance of
these steels is substantially better than that of carbon steel with or without copper addition.
When properly exposed to the atmosphere, these steels can be used bare (un-coated) for
many applications.

ASTM A563M Heavy Hex Nuts (Metric) for use with ASTM A325M Bolts

 

This ASTM A563 and ASTM A563M heavy hex nuts specification covers chemical and
mechanical requirements for eight property classes of hex and hex-flange carbon and alloy
steel nuts for general structural and mechanical uses on bolts, studs, and other externally
threaded parts.

 

Note 1: Throughout this specification, the term class means property class.

 

Note 2: Requirements for the four classes 5, 9, 10, and 12 are essentially identical with
requirements given for these classes in ISO 898/II. Requirements for Classes 8S and 10S
are essentially identical with requirements in an ISO 4775 Hexagon Nuts for High-Strength
Structural Bolting with Large Width Across Flats, Product Grade B, Property Classes
8 and 10. Classes 8S3 and 10S3 are not recognized in ISO standards.

 

1.2 Classes 8S3 and 10S3 nuts have atmospheric corrosion resistance and weathering
characteristics comparable to those of the steels covered in Specification A 588/A 588M.
The atmospheric corrosion resistance of these steel's substantially is better than that of
carbon steel with or without copper addition. and when properly exposed to the atmosphere,
these steels can be used bare (un-coated) for many applications.

 

1.3 The nut size range for which each class is applicable is given in the table on mechanical requirements.

Notes:

1. The nuts will generally conform to ANSI B18.2.4.1M - Metric Heavy Hexagonal Nuts

2. Thread will conform to class 6H of ANSI B1.13M for Coarse Series

3. Material & Heat Treatment: To achieve mechanical properties of Properties Class 8S or 10S of
ASTM A563M.

4. Nuts of Property Class 8S are used with bolts of ASTM A325M - Type 1 (uncoated). Nuts of Property
Class 10S are used with bolts of ASTM A325M - Type 1(Zinc- coated) (in general nuts of a higher
property class can replace nuts of a lower property class in a joint).

5. In Bolt/Nut assembly, tightening should be done by rotation of nut.

6. Sizes in brackets are non preferred standards.

7. All dimensions are in millimeters.
