As per IS:800-1984, the minimum pitch of rivets in a row is recommended as the diameter of the rivet times

Rivet Pitch Recommendation IS:800-1984 Explained
In structural steel design, the pitch of rivets is a crucial parameter. It defines the distance between the centers of adjacent rivets placed in the same row or gauge line.
The Indian Standard code IS:800-1984, which provides the rules for the use and erection of structural steel, sets specific requirements for rivet pitch. These requirements are essential for ensuring the strength, durability, and proper functioning of riveted connections.
IS:800-1984 recommends a minimum value for the pitch of rivets in a row to maintain structural integrity and facilitate proper load distribution. This minimum pitch ensures that there is sufficient material between adjacent rivet holes and provides adequate grip for the connected plates.
Specifically, the code states that the minimum pitch of rivets in any row should not be less than 2.5 times the nominal diameter of the rivet.
Let $d$ represent the nominal diameter of the rivet.
The minimum pitch ($p_{min}$) according to IS:800-1984 is therefore:
$$ p_{min} = 2.5 \times d $$
This means the minimum pitch is determined by multiplying the rivet's diameter by the factor 2.5.

As per IS 800, the minimum pitch of rivets in a row is recommended as:
The distance between the centre of two consecutive rivets measured along a row of rivets is known as ______.
If the working stress in bearing in power driven rivets is 300 N/mm2 and a double riveted double cover butt joint is used to connect plates of 12 mm thick, then the strength of rivet in bearing is
(Given: The nominal diameter of rivet = 22 mm)
When the maximum distance between centres of two adjacent rivets connecting the members subjected to either compression or tension exceed the maximum pitch, then the additional rivets which are not subjected to the calculated stress are used, and are known as
