IS 1929:1982 is the Indian Standard (BIS) for rivets for general purposes (below 12 mm diameter). 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.

! 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.

Key Differences
≠IS 1929 is exclusively metric, whereas key equivalents like ASME B18.1.1 and the historical BS 4620 are inch-based, leading to different standard sizes and tolerances.
≠IS 1929 specifies multiple standard angles (60°, 90°, 120°) for countersunk heads, while ASME B18.1.1 focuses on 80°-82° and 100° angles.
≠Material specifications in IS 1929 refer directly to other Indian Standards (e.g., IS 226 for steel), while international standards refer to their respective national or international material codes (e.g., ASTM, SAE, ISO).
≠Proportions for rivet heads of the same nominal diameter can vary. For a 6 mm snap head rivet, the head diameter in IS 1929 is 10.5 mm, whereas in DIN 124 it was 12 mm.
Key Similarities
≈All standards cover small-diameter solid rivets intended for general-purpose fastening, as opposed to high-strength structural applications.
≈The range of specified nominal shank diameters is very similar, typically covering from around 1.6 mm up to 10 mm (or its inch equivalent).
≈Common head types like Round (Snap), Pan, and Countersunk heads are defined and dimensioned in IS 1929 and its international counterparts.
≈The standards provide comprehensive dimensional tables specifying nominal sizes and tolerances for shank diameter, head diameter, head height, and length.
