Zogulitsa

Zatsopano

Makulidwe a Type I Cross Recessed Pan Head Screws (ASTM F837, F468)

Onetsetsani kukhazikika kodalirika ndi Type I Cross Recessed Pan Head Screws, kukwaniritsa miyezo ya ASME B 18.6.3 - 2013. Ndi zomangira zake zolimba komanso kuyika kosavuta, zomangira izi ndizoyenera kugwiritsa ntchito mosiyanasiyana m'mafakitale.

Chitsanzo:ASME B 18.6.3

Tumizani Kufunsira

Mafotokozedwe Akatundu

Kutsatira Kwanthawi Zonse:Mitundu ya I Cross Recessed Pan Head Screws imagwirizana ndi zomwe zafotokozedwa mu ASME B 18.6.3 - 2013, kuwonetsetsa kusasinthika komanso kugwirizira pamapulogalamu onse. Kukumana ndi miyezo ya ASTM F837 ndi F468, zomangira izi zimatsimikizira kudalirika ndi magwiridwe antchito.

Pan Head Design:Zopangidwa ndi kasinthidwe ka mutu wa poto, zomangira izi zimapereka mawonekedwe otsika okhala ndi malo osalala. Kapangidwe kameneka kamapereka malo okwanira olumikizirana pogawira mphamvu zonyamula katundu, kukulitsa bata komanso kupewa kuwonongeka kwa pamwamba.

Cross Recessed Drive:Pokhala ndi drive recessed drive, zomangira izi zimathandizira kukhazikitsa kosavuta ndi zida zogwirizana. The recessed drive imachepetsa kutsetsereka pakumangirira, kuonetsetsa kuti kumangirizidwa kotetezeka komanso kuchepetsa chiwopsezo cha kuwonongeka kwa mutu wa screw.

Ntchito Zosiyanasiyana:Type I Cross Recessed Pan Head Screws ndi yoyenera kugwiritsa ntchito zosiyanasiyana, kuphatikiza zamagetsi, makina, ndi mipando. Mapangidwe awo osunthika komanso magwiridwe antchito odalirika amawapangitsa kukhala ofunikira pazofunikira zosiyanasiyana.
