Makulidwe a Slotted Close Tolerance 100-deg Flat Countersunk Head Screws (Zopangira Makina Okha) (ASTM F837 F468)

Fikirani mwatsatanetsatane ndi kudalirika ndi Slotted Close Tolerance 100-deg Flat Countersunk Head Screws (Machine Screws Only) yogwirizana ndi ASME B 18.6.3 - 2013 miyezo. Yang'anirani momwe amagwirira ntchito mosasinthasintha pamapulogalamu omwe amafunikira kwambiri.

Chitsanzo:ASME B 18.6.3

Tumizani Kufunsira

Mafotokozedwe Akatundu

Zofunikira:ASME B 18.6.3 - 2013 yogwirizana ndi Slotted Close Tolerance 100-deg Flat Countersunk Head Screws (Machine Screws Only) amatsatira miyezo yolondola, kuwonetsetsa kuti magwiridwe antchito ndi ogwirizana ndi zida zamakina. Kulekerera kwawo kwapafupi kumachepetsa kusiyanasiyana, kumapangitsa kudalirika kwazinthu zofunikira.

Kumanga Kwamphamvu:Zopangidwa ku ASTM F837 ndi F468, zomangira izi zimadzitamandira ndi zomangamanga zolimba zomwe zimapirira kupsinjika kwakukulu ndi katundu wama torque. Amapangidwa kuti azikhala olimba, amapambana m'malo ovuta kwambiri a mafakitale, omwe amapereka ntchito kwanthawi yayitali popanda kusokoneza kukhulupirika.

Msonkhano Wothandiza:Ndi kasinthidwe kawo ka slotted drive, zomangira izi zimathandizira njira zolumikizirana bwino, zomwe zimalola kukhazikitsa mwachangu komanso popanda zovuta pogwiritsa ntchito zida zokhazikika. Kusavuta kugwiritsa ntchito uku kumachepetsa nthawi yocheperako komanso ndalama zogwirira ntchito, kukulitsa zokolola popanga ndi kukonza ntchito.

Ntchito Yosiyanasiyana:Zopangira makina opangira zomangira, zomangira izi zimapeza zofunikira m'mafakitale osiyanasiyana, kuphatikiza zamagalimoto, zakuthambo, ndi kupanga makina. Kusinthasintha kwawo komanso kudalirika kwawo kumawapangitsa kukhala magawo ofunikira kwambiri pakusunga ndi kumangirira magawo ndi zida zofunikira.
