What diameter range of rivets is covered by IS 2999?

It covers mild steel rivets from 12 mm up to 48 mm in diameter.

What is the preferred material for these rivets?

The material should typically conform to IS 1148 (Hot rolled steel rivet bars for structural purposes).

What types of rivet heads are specified in this standard?

The standard specifies snap head, pan head, countersunk head, and rounded countersunk head rivets.

Can these rivets be used for structural steelwork?

Yes, they were historically the primary fasteners for structural steelwork and bridges, though modern practices use bolts and welding.

This standard specifies the dimensions, tolerances, and material requirements for mild steel rivets of 12 mm to 48 mm diameter used in general engineering and structural applications. It covers various head types including snap, pan, and countersunk heads. While riveting is largely obsolete in modern construction, this code remains relevant for repair, maintenance of heritage structures, and specific mechanical assemblies.

Specifies requirements for mild steel rivets of 12 to 48 mm diameter for general engineering purposes.

Practical Notes

Riveting is mostly obsolete in modern steel structures, having been replaced by high-strength friction grip (HSFG) bolts and welding.

When calculating the required grip length of the rivet, adequate allowance must be made to form the driven head and fill the hole completely.

Do not use these rivets for pressure vessels or boilers; boiler rivets are covered separately under IS 1928.
