Explanation:

As per IS 800:2007

Minimum Pitch, Pmin = 2.5 d, where d = nominal diameter of bolt

For Compression: Maximum pitch, Pmax = min (12t, 200 mm)

For tension: Maximum pitch, Pmax = min (16t, 200 mm)

Where t = thickness of the thinner plate

Further, if bolts are staggered and gauge distance ≤ 75 mm then maximum pitch can be increased by 50% because less gauge distance and staggering of bolt reduce the chances of separation of two plates between bolts.
