Nā Ana o ke ʻano I Cross Recessed Pan Head Screws (ASTM F837, F468)

E hōʻoia i ka hoʻopaʻa pono ʻana me Type I Cross Recessed Pan Head Screws, e hālāwai ana me nā kūlana ASME B 18.6.3 - 2013. Me kā lākou hana paʻa a me ka maʻalahi o ka hoʻokomo ʻana, kūpono kēia mau wili no nā noi like ʻole ma nā ʻoihana.

Hoʻohālike:ASME B 18.6.3

E hoʻouna i ka nīnau

Hōʻike huahana

Hoʻokō maʻamau:ʻO Type I Cross Recessed Pan Head Screws e like me nā kikoʻī koʻikoʻi i hōʻike ʻia ma ASME B 18.6.3 - 2013, e hōʻoiaʻiʻo ana i ka paʻa a me ka hoʻokō ʻana i nā noi. E hui ana i nā kūlana ASTM F837 a me F468, hōʻoia kēia mau wili i ka hilinaʻi a me ka hana.

Pan Head Design:Hoʻolālā ʻia me ka hoʻonohonoho ʻana o ke poʻo pan, hāʻawi kēia mau wili i kahi hiʻohiʻona haʻahaʻa haʻahaʻa me kahi ʻili palahalaha. Hāʻawi kēia hoʻolālā i kahi wahi hoʻopili nui no ka puʻunaue ʻana i nā ikaika ukana, hoʻonui i ke kūpaʻa a pale i ka pōʻino o ka ʻili.

Kea i hoʻokuʻu ʻia:Ke hōʻike nei i kahi kaʻa hoʻokuʻu kea, hoʻomaʻamaʻa kēia mau wili i ka hoʻokomo maʻalahi me nā mea hana kūpono. ʻO ke kaʻa i hoʻokuʻu ʻia e hōʻemi i ka paheʻe ʻana i ka wā o ka paʻa ʻana, e hōʻoia ana i ka hoʻopaʻa paʻa ʻana a me ka hōʻemi ʻana i ka pōʻino o ke poʻo wili.

Mea Hoʻohana Nui:ʻO Type I Cross Recessed Pan Head Screws he kūpono ia no ka nui o nā noi, e like me ka uila, nā mīkini, a me ka hui hale. ʻO kā lākou hoʻolālā maʻalahi a me ka hana hilinaʻi e pono ai lākou no nā pono paʻa like ʻole.
