L = δ + 1.4 × d
d: Umurambararo wa diameter, δ : Kuzunguruka ubunini
● Uburebure bwuzuye bwumutwe uzengurutse umutwe wa rivet inkoni = 1.65 ~ 1.7d + L + 10% yubunini bwuzuye bwisahani.
● Uburebure bwuzuye bwa kimwe cya kabiri cyumutwe wa rivet inkoni = 1.1d + L + 10% yubunini bwuzuye bwisahani.
● Uburebure bwuzuye bwa countersunk rivet inkoni = 08d + L + 10% yubunini bwuzuye bwisahani.
d = diameter
L = ubunini bwuzuye
d.L ni mm
