Standard Specification for Rivets, Steel, Structural

ABSTRACT
This specification covers the chemical composition, mechanical (Brinell hardness), dimensional, and visual inspection requirements, and associated test methods for steel rivets used for structural fabricating purposes. The steel used to make the rivets shall be manufactured by the open-hearth, basic-oxygen, or electric-furnace process, and the corresponding rivets shall be made by the hot or cold heading process and are expected to be hot driven. The rivets are available in the following grades: Grade 1, carbon steel rivets for general purpose use; Grade 2, carbon manganese steel rivets for use with high strength carbon and high strength low alloy structural steels; and Grade 3, weathering steel rivets.
SCOPE
1.1 This specification covers three grades of steel rivets in diameters from ½ to 1½ in. inclusive, for structural fabricating purposes. The grades are as follows: GradeDescription 1Carbon steel rivets for general purpose use 2Carbon manganese steel rivets for use with high strength carbon and high strength low alloy structural steels  3Weathering steel rivets
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
