A563M-10S HEAVY HEX NUTS M90 M64 BLACK
Specification
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.
