L= δ+ 1.4 × d
d: Umwanya w'umurambararo, δ： Ubunini bw'umurambararo
● Uburebure bwose bw'agakoresho k'umutwe gafite uruziga = 1.65 ~ 1.7d + L + 10% by'ubunini bwose bw'isahani.
● Uburebure bwose bw'agakoresho k'umutwe kari ku gipimo cya semi countersunk = 1.1d + L + 10% by'ubunini bwose bw'isahani.
● Uburebure bwose bw'inkoni ya rivet icukurwaho = 08d + L + 10% by'ubunini bwose bw'isahani.
d = umurambararo wa rivet
L = ubunini bw'isahani yose
d. L ni mm
