Li-screws tse ntšo ke li-fasteners tse etselitsoeng ho etsa likhoele ha li ntse li koaheloa ka thepa e kang tšepe, polasetiki le lehong. Li-screw tsena hangata li sebelisoa lits'ebetsong moo ho hlokehang khokahanyo e matla, e sa feleng, joalo ka indastering ea kaho, ea likoloi le ea lisebelisoa tsa elektroniki.

Li-screws li entsoe ka tšepe ea boleng bo phahameng ea carbon 'me li koahetsoe ka oxide e ntšo, e fanang ka khanyetso khahlanong le mafome le kutu. Qetello e ntšo e boetse e fa li-screws ponahalo e khahlehang, e boreleli e loketseng mefuta e fapaneng ea likopo.

One of the key advantages of black self tapping screws is their ability to create threads without the need for pre-drilling or tapping. This feature makes them easy to use and saves time during installation. Additionally, the screws are designed with a sharp, pointed tip that allows them to easily penetrate materials and start the thread-forming process.

Ka kakaretso, li-screws tse ntšo tsa "self tapping" ke tharollo e ka tšeptjoang le e tenyetsehang e ka sebelisoang mefuteng e mengata ea lits'ebetso.
