ʻO ke kala Zinc Plated Pan Head Self-Drilling Screw Me ka Washer (Phillips Wafer Flange Head Self-Drilling Screw)

1. Nā māla kūpono a me nā kūlana huahana

Hana ʻia ka huahana e like me GB/T15856.2 Chinese national standard a hele mai me ka washer flange plate, e hoʻonui ai i ka wahi kaomi i ka wā e paʻa ai a pale i ka paheʻe a me ka wehe. Hoʻohana nui ʻia ia i nā kiʻi kila māmā, nā linings pepa kala, nā mea uila uila, nā mea komo puka a me nā puka makani, nā pale hao, a me ka hui pū ʻana o ka hui. Hoʻokuʻu ʻia ia i ka Hikina Hikina Hema, ka Middle East, ʻApelika a me nā mākeke lako a me nā hale kūʻai ʻē aʻe i ka makahiki āpau. ʻO ka piko o ka drill point kona ʻoki ʻoki ponoʻī, kahi e hoʻopau ai i ka pono no ka hana mua ʻana a hiki ke hoʻoheheʻe pololei ʻia ma o 2 ~ 5mm ʻāpana kila lahilahi. He mea hoʻopili hoʻopaʻa honua no nā hale kila māmā i loko.

2. Nā lako maka a me ka ʻenehana hana

Koho ʻia ke kila kalapona kiʻekiʻe, a ua ʻae ʻia ka mālama wela hoʻopau holoʻokoʻa. He ʻoʻoleʻa koʻikoʻi ka lae drill, a ʻoi aku ka ʻoi a paʻakikī ke ʻoki ʻana i ka wēlau a haʻihaʻi ma ka wahi drill. Kaʻina hana: He ʻumi kaʻina hana e like me ke kaha kiʻi ʻana o nā mea maka, annealing, phosphating, kiʻi maikaʻi, ke poʻo anu, ka hana ʻana, ka ʻōwili ʻana i ka milo, ka hana ʻana i ka wela, ka plating zinc, a me ka hoʻopili. Hoʻohui ʻia ke poʻo anti-skid tooth washer a me screw i mea e pale ai i ka mea hana extruded mai ka paheʻe ʻana i ka wā e hui ai. ʻAʻahu a maʻamau ka pitch thread, a pili paʻa ka ʻili kila i hoʻopaʻa ʻia, a kūpaʻa nā niho i ka wehe ʻana a hāʻule ma hope o ka haʻalulu lōʻihi. ʻOi aku ka mānoanoa a me ka mānoanoa ka uhi ʻana o ka zinc plated.

3. Nā pono kumu waiwai

Hoʻohui ʻia ka mea holoi lole anti-slip: ʻO kahi pōʻai o nā ʻāpana anti-slip ma ka lalo o ka flange nahu i ka ʻili o ka papa ma hope o ka hoʻopaʻa ʻana, me ka pale ʻana i nā wili mai ka wehe ʻana, e hoʻopau ana i ka pono e hoʻokomo i kahi mea holoi pālahalaha ʻokoʻa, a pōkole ka manawa hana.

ʻO ka ʻeli ʻana ponoʻī me ka ʻole o ka wili mua ʻana: hoʻopau ka piko drill point i ka wili ʻana, ka paʻi ʻana, a me ka laka ʻana i ka hele hoʻokahi. He kūpono ia no nā papa zinc plated, nā ʻāpana hao i ʻōwili ʻia i ke anuanu, a me nā kiʻi kila kila, a ʻoi aku ka maikaʻi o ka hoʻonohonoho ʻana o nā panela lahilahi.

4. ʻO ka mālama ʻana i ka maikaʻi a me nā lawelawe kākoʻo

ʻO ka piha piha o nā kiko'ī i nā manawa a pau, hoʻounaʻia nā kauoha maʻamau i loko o nā hola 48, a hiki keʻaeʻia nā kauoha hoʻohālike a me nā kauoha hoʻopuka piha piha. ʻO ka paʻakikī o ka drill point, anti-slip serration shape, thread accuracy, and coating adhesion e nānā pono ʻia ma mua o ka haʻalele ʻana i ka hale hana, a hoʻopau ʻia nā huahana kīnā ʻole me nā ʻaoʻao ʻokiʻoki, nalo nā niho, a me nā pale kīnā ʻole. Hiki ke hoʻolako ʻia i nā pūʻulu piha me ka helu hexagonal drill a me ka countersunk head drill point, a me nā mea hoʻopaʻa hoʻokahi; Kākoʻo ia i ka hoʻolōʻihi ʻole ʻia a me ke ʻano niho kūikawā i ka hoʻoheheʻe ʻana iā ia iho, a me ka hiki ke hana paʻa e hōʻoia i ka hoʻopiha hou ʻana no nā mea kūʻai aku ma waho.
