Precision Tapping:82 ° Slotted Flat Countersunk Head Tapping Screws, e boletsoeng ho ASME B 18.6.3 - 2013, e entsoe bakeng sa ho tlanya ka mokhoa o nepahetseng, ho netefatsa hore ho etsoa khoele e nepahetseng le e tsitsitseng. Moralo oa hlooho e bataletseng oa countersunk o fana ka pheletso e phoroselang, e fokotsang ponahalo ea bokaholimo le ho ntlafatsa boipiletso bo botle ba likopano.

Kemiso e Sebetsang:Ka moralo oa tsona oa hlooho, li-screws tsena li thusa ho kenya le ho tlosoa ka katleho, ho nolofalletsa mekhoa ea kopano e potlakileng le e se nang mathata. The angle 82 ° e tiisa ho sebelisana hantle le screwdrivers kapa bits, ho matlafatsa taolo le ho fokotsa kotsi ea cam-out nakong ea ho tiisa.

Tšebetso e tšoarellang:E entsoe ka thepa ea boleng bo holimo, li-screws tsena li fana ka nako e telele le botsitso lits'ebetsong tse fapaneng. Li fana ka litharollo tse tiileng tse ka tšeptjoang le tse tšoarellang nako e telele, tse tlatsetsang botsitso le botšepehi ba mehaho e kopaneng kapa likaroloana.
