Pitch of Rivets

There are the following details of pitch as per Indian Standard Specifications:

Minimum Pitch

The distance between centres of rivets should not be less than 2.5 times the nominal diameter of the rivets, i.e.

s ≥ 2.5 d_n

Figure (a) : Minimum Pitch

Maximum Pitch

The distance among any two adjacent rivets (including tacking rivets) shall not exceed 32 t or 300 mm (whichever is less); t being the thickness of the thinner outside plate.

s ≤ 16 t or 200 mm (whichever is less) in tension members, and

s ≤ 12 t or 200 mm in compression members.
