Countersunk Head Phillips Self Drilling Screws

Zininzi iindidi zezikrufu ezinamaphiko zokuzigoba, kodwa zonke zineempawu ezifanayo. Kukho iimpawu ezintlanu eziphambili. Le hardware ilandelayo inika iinkcukacha zeempawu ezintlanu zezikrufu ezinamaphiko zokuzibhora:

1. Ngokuqhelekileyo yenziwe ngentsimbi ye-carburized (99% yeemveliso ezipheleleyo). Isenokusetyenziswa kwintsimbi engatyiwayo okanye ngesinyithi.

2. I-self-drilling screws enamaphiko kufuneka iphathwe ngobushushu. I-Hardware ikuxelela ukuba izikrufu ze-carbon steel self-tapping screws kufuneka zenziwe nge-carburized, kwaye izikhonkwane zensimbi ezingenasici ezinezikhonkwane zamaphiko kufuneka zibe sisisombululo esiqinileyo. Ukuze wenze i-self-tapping screws ihlangabezane neempawu zomatshini kunye nokusebenza okufunwa ngumgangatho.

3. Iimveliso ze-self-drilling screw ezinamaphiko zinobulukhuni obuphezulu bomphezulu kunye nokuqina okulungileyo okungundoqo. Oko kukuthi, "ithambile ngaphakathi kwaye yomelele ngaphandle". I-hardware ikuxelela ukuba olu luphawu oluphambili lweemfuno zokusebenza kwee-self-drilling wing nails. Ukuba ubunzima bomphezulu buphantsi, abukwazi ukujijwa kwi-matrix; ukuba undoqo unokuqina okungahambi kakuhle, uya kwaphuka nje ukuba ukrwelwe kwaye awunakusetyenziswa. Ke ngoko, "ithambile ngaphakathi kwaye iqinile ngaphandle" zizikrufu zokuzibhobhoza ezinezikhonkwane zamaphiko ukuhlangabezana neemfuno zokusebenza.

4. Umphezulu we-Best Self Drilling Screw With Wings iimveliso zifuna unyango lokukhusela umphezulu, ngokuqhelekileyo unyango lwe-electroplating. I-hardware ikuxelela ukuba umphezulu wezinye iimveliso kufuneka uphathwe nge-phosphate (phosphating). Umzekelo: Izikrufu zokuzibhora ezinezikhonkwane zamaphiko kwiibhodi zodonga ubukhulu becala zinephosphated
