L= δ+ 1.4 × d

d: Rivet diameter, δ： Riveting thickness

● Full length of semicircular head rivet rod = 1.65 ~ 1.7d + L + 10% of the total thickness of the plate.
● Full length of semi countersunk head rivet rod = 1.1d + L + 10% of the total thickness of the plate.
● Full length of countersunk rivet rod = 08d + L + 10% of the total thickness of the plate.

d = rivet diameter

L = total plate thickness

d. L is mm
