Ka mokhoa o hlophisitsoeng, li-fasteners hangata li na le hlooho le shank, li fihlella ho tiisa ka likhoele kapa meaho e meng ea mochini. Li-fasteners tse tloaelehileng haholo li kenyelletsa liboutu, li-screw, linate, li-washer le li-rivets.

Khetho ea thepa ea li-fasteners e ama ka kotloloho ts'ebetso ea bona le lits'ebetso tse sebetsang. Li-fasteners tse tloaelehileng tsa carbon steel li fana ka theko e tlaase le matla a itekanetseng, e leng se etsang hore li sebelisoe haholo lits'ebetsong tse akaretsang tsa indasteri. Li-fasteners tsa tšepe tse sa hloekang li fana ka khanyetso e ntle ea kutu 'me li loketse ho sebelisoa libakeng tse mongobo kapa tse senyang lik'hemik'hale.
