Gonye i cylindrical, threaded shaft ine helical groove yakachekwa pamusoro payo. Iroworm giya ivhiri rine mazino rinosangana nehonye, ​​richishandura kutenderera kwegonye kuita mutsara wekufamba kwegiya. Mazino ari pagiya rehonye anochekwa nekona rinoenderana nekona yehelical groove pane gonye.

Mumuchina wekugaya, gonye negonye giya rinoshandiswa kudzora kufamba kwemusoro wekugaya kana tafura. Gonye rinowanzo fambiswa nemota, uye parinotenderera, rinosangana nemazino egiya rehonye, ​​zvichiita kuti giya rifambe. Kufamba uku kunowanzo kuve kwakanyatsojeka, zvichibvumira kumira kwakarurama kwemusoro wekugaya kana tafura.

Imwe mukana wekushandisa gonye negonye giya mumashini ekugayo nderekuti inopa yakakwira mwero wemuchina mukana, ichibvumira mota idiki kutyaira gonye ichiri kunyatsoita kufamba chaiko. Pamusoro pezvo, nekuti mazino egiya rehonye anobatana nehonye pakona isina kudzika, kune kushomeka kukweshera uye kupfeka pazvikamu, zvichikonzera hupenyu hurefu hwebasa rehurongwa.
