Izixhobo ezijikelezayo, ekwaziwa njengeegiya ze-helical, zibonelela ngeenzuzo ezininzi xa zisetyenziswa kwiinkqubo zothumelo oluzenzekelayo:

1. Ukusebenza okugudileyo: Imilo ye-helix yamazinyo egiya ivumela ukusebenza kakuhle kunye nokungcangcazela okuncinci xa kuthelekiswa neegiya ezithe tye.
2. Ukubaleka okuzolileyo: Ngenxa yokudibana okuqhubekayo kwamazinyo, iigiya ezijikelezayo zibaleka ngokuzolileyo kwaye zivelise ingxolo encinci kunezinye zazo ezinamazinyo athe tye.
3. Ubuchule obuphezulu: Isenzo sokugqithelana kweegiya ze-helical sivumela ukuhanjiswa kwamandla aphezulu, njengoko amazinyo amaninzi enxibelelana, oku kuthetha ukutyibilika okuncinci kunye nokulahleka kwamandla.
4. Umthamo Onyusiweyo Womthwalo: Uyilo lweegiya ezijikelezayo lunokuphatha imithwalo ephezulu ngaphandle kwesidingo sobukhulu begiya, oluluncedo ngakumbi kuyilo olubambeneyo.
5. Ubomi obude: Ukwabiwa ngokulinganayo kwamandla kumazinyo egiya kubangela ukuguga okuncinci kunye nobomi obude begiya.
6. Ukuhanjiswa kweTorque ephezulu:Izixhobo ezijikelezayoinokudlulisa i-torque ephezulu kwindawo encinci, efanelekileyo kwizicelo apho indawo iphezulu.
7. Ulungelelwaniso olungcono: Bancedisa ukulungelelaniswa okungcono kwee-shafts, ukunciphisa imfuno yamacandelo okulungelelanisa okongeziweyo kunye nokwenza lula ukuyila ngokubanzi.
8. Ulawulo lwe-Axial Thrust: I-thrust eyenziwe ngexesha lokusebenza yi-axial, enokulawulwa ngokulula ngoyilo olufanelekileyo lokuthwala.
9. Ukufaneleka kwezantya eziPhezulu: Izixhobo ze-Spiral zifanelekile kwizicelo zesantya esiphezulu ngenxa yokukwazi ukuphatha imithwalo ephezulu kunye nokugcina ukusebenza kakuhle.
10. Ukuxhathisa koMthwalo woMothuko: Banokuyifunxa ngcono imithwalo yokothuka ngenxa yokuzibandakanya ngokuthe ngcembe kunye nokungaboleki kwamazinyo.
11. Ubuchule beSithuba: Kumthamo onikiweyo wokuhambisa amandla, iigiya ezijikelezayo zinokubumbana ngakumbi kunezinye iindidi zegiya.
12. ULondolozo oluPhantsi: Inkqubo yokwenziwa echanekileyo kunye nokuhanjiswa komthwalo kubangela iigiya ezifuna ukulungiswa kancinci ekuhambeni kwexesha.
13. Ukuthembeka: Iigiya ze-Spiral ziyaziwa ngokuthembeka kwazo kwiinkqubo zothumelo oluzenzekelayo, apho ukusebenza okungaguqukiyo kubalulekile.

Ezi nzuzo zenzaizixhobo ezijikelezayoukhetho oludumileyo kwiindidi ezahlukeneyo zoomatshini kunye nezixhobo ezifuna ukuhanjiswa kwamandla okuzenzekelayo kunye nokusebenzayo.
