This standard covers the requirements for hot forged steel rivets intended for hot closing, covering a diameter range of 12 mm to 36 mm. It provides dimensional specifications, material requirements, and tolerances for snap, pan, and countersunk head rivets traditionally used in heavy structural steelwork.
Specifies requirements for rivets below 12 mm diameter for general purposes.

Practical Notes
Hot riveting is mostly obsolete in modern construction, primarily replaced by High Strength Friction Grip (HSFG) bolts and modern welding techniques.
Allowance must be mathematically added to the required grip length to account for forming the driven head and filling the clearance hole.
Proper heating temperatures must be maintained during installation to ensure the rivet becomes plastic enough to drive without burning or embrittling the steel.
