Countersunk Head Phillips Self Drilling Screws

Pali mitundu yambiri ya mapiko odzibowola okha, koma onse ali ndi mawonekedwe ofanana. Pali makhalidwe asanu akuluakulu. Zida zotsatirazi zimafotokoza za zinthu zisanu za mapiko odzibowola okha:

1. Nthawi zambiri amapangidwa ndi chitsulo chopangidwa ndi carburized (99% yazinthu zonse). Angagwiritsidwenso ntchito pazitsulo zosapanga dzimbiri kapena zitsulo zosapanga dzimbiri.

2. Zomangira zodzibowola zokha ndi mapiko ziyenera kutenthedwa. Zida zomangira zimakuuzani kuti zomangira zomangira zitsulo za kaboni ziyenera kukhala zolimba, ndipo zomangira zachitsulo zosapanga dzimbiri zokhala ndi misomali yamapiko ziyenera kukhala zolimba zolimba. Pofuna kupanga zomangira zodzipangira zokha kukumana ndi zida zamakina ndi magwiridwe antchito omwe amafunikira muyezo.

3. Zopangira mapiko zodzibowola zokha zimakhala ndi kulimba kwambiri komanso kulimba kwapakati. Ndiko kuti, “zofewa mkati ndi zamphamvu kunja”. The hardware amakuuzani kuti ichi ndi mbali yaikulu ya ntchito zofunika misomali mapiko kudzibowola. Ngati kuuma kwa pamwamba kuli kochepa, sikungalowe mu matrix; ngati pachimake chili ndi kulimba kosalimba, chimasweka chikangophwanyidwa ndipo sichingagwiritsidwe ntchito. Chifukwa chake, "zofewa mkati ndi zolimba kunja" ndi zomangira zodzibowolera zokhala ndi misomali yamapiko kuti zikwaniritse zofunikira.

4. Pamwamba pa Best Self Drilling Screw With Wings mankhwala amafunikira chithandizo chachitetezo chapamwamba, nthawi zambiri chithandizo cha electroplating. Zida zimakuuzani kuti pamwamba pa zinthu zina ziyenera kuthandizidwa ndi phosphate (phosphating). Chitsanzo: Zomangira zodzibowolera zokhala ndi misomali yamapiko pamakoma nthawi zambiri zimakhala phosphated
