DONGSHAO, moetsi ea tsebahalang oa China, o ikemiselitse ho u fa Round Head Square Neck Bolts. Re ts'episa ho u fa ts'ehetso e ntle ka ho fetisisa ka mor'a thekiso le ho fana ka thepa kapele.
Hebei Dongshao Fastener Manufacturing Co., Ltd. ke morekisi ea tsebahalang le moetsi oa liboutu tse chitja tsa square neck naheng ea China.
The Round head Square Neck bolts produced by the company is round and can be easily passed through the round hole, making installation and disassembly easier. Its neck has a square shape, hence its name. Moqapi ona o eketsa sebaka sa eona sa ho kopana le linate, kahoo o eketsa botsitso ba phetisetso ea torque.
1. Melemo ea Sebopeho le Moralo
Moralo oa Hlooho e Boreleli: Hlooho ea bolt e na le profaele e boreleli, e chitja e lumellang hore ho kenngoe ka mokhoa o se nang moroallo ka har'a masoba a chitja a phuntsoeng pele. This design not only enhances the efficiency of equipment installation and disassembly but also ensures an aesthetically pleasing appearance and improved safety.
Sebopeho se Ikhethileng sa Square Neck: Moralo o ikhethileng oa square neck o notlella ka mokhoa o sireletsehileng ka har'a sekotjana sa ho nyalana, o fana ka ts'ebetso ea ho its'oara nakong ea ho tiisa ho thibelang bolt ho potoloha. Moqapi ona o eketsa haholo sebaka sa ho ikopanya le thepa ea motheo kapa washer, ka tsela eo e ntlafatsa haholo botsitso ba phetisetso ea torque.
2. Litšobotsi tsa Thepa le Tlhahiso
Lisebelisoa tsa Premium High-Performance: Lihlahisoa tsa rona tsa mantlha li etsoa ka lisebelisoa tse tala tsa boleng bo holimo tse kang tšepe e sa hloekang le tšepe ea alloy. These materials offer excellent tensile and yield strength, ensuring the bolts resist deformation or fracture even in complex, high-load operating environments.
Advanced Surface Treatment (Dacromet Technology): Libaka tsa bolt li ka phekoloa ka theknoloji e tsoetseng pele ea Dacromet anti-corrosion coating. This process imparts superior weather resistance and exceptional oxidation and rust protection, effectively blocking environmental corrosion and exponentially extending the product's service life.
3. Mefuta e mengata e fapaneng ea likopo
Li-bolts tsa Dongshao's round head square neck bolts li bapala karolo ea bohlokoa ho tiisa likarolo ho metjhini e mengata e boima, makoloi a lipalangoang le merero ea meralo:
Likoloi le Lipalangoang: E sebelisoa haholo bakeng sa mabili a tiisang, li-axle le liforeimi tsa 'mele ha ho etsoa likoloi.
Mechini ea Boenjineri le Temo: E sebelisoa ho boloka likarolo tsa meaho mochining oa kaho, lisebelisoa tsa ho phahamisa le mechini ea sejoale-joale ea temo.
Indasteri le Kaho: E loketse lits'ebetso tsa indasteri tse hlokang khanyetso e phahameng ea ho sisinyeha ha litšisinyeho le matla a ho thibela ho lokoloha, joalo ka sistimi ea ho kenya photovoltaic le meaho ea tšepe.
