Moralo o ntlafalitsoeng:82° Slotted Oval Countersunk Head Tapping Screws, joalo ka ha ho hlalositsoe ho ASME B 18.6.3 - 2013, e na le moralo o ntlafalitsoeng o etselitsoeng likopo tse sebetsang hantle le tse tšepahalang. Hlooho ea "oval countersunk" e slotted e etsa bonnete ba hore ho fela ha metsi, ho fokotsa kotsi ea ho hlaha le ho fana ka sebaka se boreleli ha se kenngoa.

Precision Tapping:Li-screws tsena li entsoe ka mokhoa o nepahetseng, 'me li etsa hore ho be le masoba a khoele ka nepo le ka mokhoa o tsitsitseng. Moqapi oa hlooho ea 82 ° o thusa ho kenya le ho tlosoa habonolo, ho nolofatsa ts'ebetso ea kopano le ho boloka nako ea bohlokoa le boiteko.

Lisebelisoa tsa boleng bo holimo:E entsoe ka thepa ea boleng bo holimo, li-screws tsena li fana ka nako e telele le bophelo bo bolelele maemong a fapaneng a ts'ebetso. Li fana ka ho tiisa ka mokhoa o sireletsehileng le o tsitsitseng, ho kenya letsoho ho tšepahala ka kakaretso le ho tšepahala ha likarolo tse kopaneng.

Tšebeliso e fapaneng:Li loketse mefuta e mengata ea lits'ebetso ho pholletsa le liindasteri tse kang tsa kaho, tsa likoloi le tsa elektroniki, li-screw tsena li fana ka ts'ebetso e ikhethang le ho feto-fetoha ha maemo. Ebang ke ka lehong, tšepe, kapa polasetiki, li tiisa hore ho na le likhokahano tse ka tšeptjoang le tse matla.
