Lisebelisoa tsa Matla a Liindasteri:Li-heavy hex screws, tse hlahang ho Lethathamo la 7, li etselitsoe lisebelisoa tsa indasteri tse hlokang tharollo e tiileng ea ho tiisa. Li-screws tsena li fana ka matla a matla le ho tšoarella, li etsa hore li tšoanele mechini e boima, lisebelisoa le likopano tsa meralo.

Lisebelisoa tsa Premium:E entsoe ka thepa ea boleng bo holimo e kang carbon steel, alloy steel, kapa tšepe e sa jeleng paate, li-screw tse boima tsa hex li fana ka ts'ebetso e ntle haholo tlas'a maemo a feteletseng. Kaho ea bona ea boleng bo holimo e tiisa ho tiea ho ts'epahalang maemong a thata, ho netefatsa ts'ebetso ea ts'ebetso le ts'ireletso.

Moralo o ntlafalitsoeng:Li-heavy hex screws li na le boholo bo boholo ba hlooho ha bo bapisoa le li-screw tse tloaelehileng tsa hex, tse fanang ka bokaholimo bo eketsehileng le matla a ntlafetseng a ho tiisa. Moralo ona o ntlafatsa botsitso mme o fokotsa kotsi ea ho hlepha kapa ho hloleha, e leng ea bohlokoa bakeng sa lits'ebetso tsa bohlokoa maemong a indasteri.

Lisebelisoa tse fapaneng:Ka mefuta e mengata e fapaneng ea boholo ba likhoele, bolelele, le limaraka tse fumanehang, li-screws tse boima tsa hex ke li-fasteners tse fapaneng tse loketseng lits'ebetso tse fapaneng tsa indasteri. Hore na o boloka likarolo tsa mochini o boima kapa o kopanya likarolo tsa meralo, likurufu tsena li fana ka matla le ts'epahalo e hlokahalang bakeng sa mosebetsi.

Tšireletso ea Corrosion:Ho mamella maemo a thata a ts'ebetso, li-screws tse boima tsa hex li ka koaheloa ka lithapo tse thibelang kutu joalo ka zinc plating, galvanization kapa manyolo a tlhaho. Liaparo tsena tse sireletsang li fana ka khanyetso ea nako e telele khahlanong le kutu, ho netefatsa nako e telele ea li-fasteners le mehaho eo ba e tšehetsang.

Tumellano le Setifikeiti:Li-heavy hex screws tse entsoeng ho latela maemo a indasteri li etsa liteko tse matla le lits'ebetso tsa netefatso ea boleng ho netefatsa hore li lumellana le litlhaloso le litlhoko tsa ts'ebetso. Batla lihlahisoa tse netefalitsoeng ho netefatsa ts'epo le khotso ea kelello lits'ebetsong tsa hau tsa indasteri.

Tataiso ea Setsebi:Ha u khetha li-screw tse boima tsa hex bakeng sa litlhoko tsa hau tse ikhethileng tsa indasteri, batla tataiso ho litsebi mabapi le tharollo ea ho tiisa. Li ka u thusa ho khetha li-screw tse nepahetseng tse ipapisitseng le lintlha tse kang litlhoko tsa mojaro, maemo a tikoloho, le tšebelisano ea thepa, ho netefatsa ts'ebetso e nepahetseng le polokeho.
