Hexagonal bolts ane hexagonal forged head ane shinda dzemuchina, anoshandiswa pamwe chete nenzungu kugadzira musanganiswa wenzungu nemabhaudhi, anoshandiswa sezvisungo kuchengetedza majoini mativi ese epamusoro. Izvi zvakasiyana nescrew yakarukwa, asi inotenderera yakatenderedza axis yayo, inobaya pamusoro, uye inogadziriswa. Hexagonal mabhaudhi anozivikanwawo secap screws uye mabhaudhi emuchina. Madhayamita awo anowanzo kuve pakati pe ½ kusvika 2 ½ ”. Anogona kusvika masendimita makumi matatu pakureba. Mabhaudhi anorema ane hexagonal uye mabhaudhi emuumbirwo ane madhindindi akanaka ekushivirira. Mamwe masaizi akati wandei asiri akajairwa anogonawo kugadzirwa zvinoenderana nezvinodiwa kuti asangane nezvinangwa zvakasiyana. kuvakwa kwemabhiriji, zviteshi, migwagwa mikuru, uye zvivakwa.
