Li-screws tsa hlooho ea cap, tse tsejoang hape e le li-socket head screws, ke mofuta oa fastening o sebelisoang haholo lits'ebetsong tse fapaneng tsa indasteri. Li khetholloa ke hlooho ea tsona ea cylindrical e nang le top top le hexagonal socket, e lumellang ho tiisa habonolo ka Allen wrench kapa hex key.

Ho Ningbo Zhenkun Machinery Co., Ltd, re etsa li-cap head screws tsa boholo bo fapaneng le lisebelisoa ho fihlela litlhoko tsa bareki ba rona. Li-screws tsa rona li entsoe ka thepa ea boleng bo holimo, joalo ka tšepe e sa jeleng paate, tšepe ea khabone, le tšepe ea alloy, ho netefatsa ho tšoarella le matla a tsona.

Li-screws tsa hlooho li na le lits'ebetso tse ngata, ho kenyeletsoa indastering ea likoloi, indasteri ea sefofane, indasteri ea kaho, le tse ling. Hangata li sebelisoa likopanong moo ho lakatsehang sebaka se phoroselang, kaha bokaholimo ba sekoti bo fana ka ponahalo e boreleli.

Ntle le ponahalo ea bona e boreleli, li-screws tsa hlooho tsa cap li boetse li fana ka torque e ntle haholo le matla a ho ts'oara, e leng se etsang hore e be khetho e tsebahalang bakeng sa lits'ebetso tse phahameng haholo. Sokete ea bona ea hexagonal e boetse e fana ka phetiso e ntle ea torque mme e fokotsa kotsi ea ho hlobola ha e bapisoa le mefuta e meng ea li-screws.
