The specifications for tubular rivets include nominal diameters ranging from Φ0.7 mm to Φ20 mm (with Φ1.2 mm and Φ14 mm being non-preferred sizes) and nominal lengths (L) from 2 mm to 40 mm. Materials include carbon structural steel (such as grade 20) and copper and its alloys (such as T2, H62, and H96), while surface treatments include zinc plating with passivation, tin plating, and silver plating with passivation.
The reference standards are GB/T 975-1986 (subsequently superseded by JB/T 10582-2006) and GB/T 116-1986; tubular rivets are used for riveting non-metallic materials in applications not subject to load.
