Waqtigan xaadirka ah, qeexitaannada lawska rivet ee heerka qaranka waxaa ka mid ah m3 M4 M5 M6 M8 M10 M12. Xaqiiqdii, M6 iyo M8 ayaa lagu talinayaa, sababtoo ah haddii duntu yar tahay, si toos ah ayaa loogu dhejin karaa substrate-ka si loogu xidho. Haddii duntu weyn tahay, miisaanka boolku aad buu u kordhi doonaa, xoogga isku xirka lawska rivet-kana wuu kordhi doonaa xaddidan, taas oo ah, isku-xidhku ma aha mid aad u macquul ah.
Waxaa laga arki karaa kor ku xusan in lawska rivet si weyn loogu isticmaali karo substrate-ka aluminiumka ee dhumucdiisu kala duwan tahay ama saxannada birta ah ee dhumucdoodu tahay 1-2.5mm. Gaar ahaan, isku xirka lawska rivet-ka birta ah ee qaybaha aluminiumka ayaa meesha ka saaraya dhibka ku jira ku dhejinta saxannada birta ah gudaha, waxqabadkeedana si weyn ayaa loo hagaajiyay.
