Uthini umahluko phakathi kweentloko zescrew ezichasene ne-countersunk kunye ne-non countersunk screw heads

I-Countersunk kunye ne-non-countersunk zintlobo ezimbini ezisisiseko zoyilo lwentloko ye-screw. Iintloko ezingaxutywanga zibandakanya iintloko ezidibanisayo, iintloko zamaqhosha, iintloko ezisilinda, iintloko ezingqukuva, iintloko zeflange, iintloko ezinehexagonal, iintloko zepani, isetyhula, isikwere, iintloko zetruss, njl.
I-countersunk screw intloko yenzelwe ukuba igungxulwe okanye ingaphantsi kancinane kumphezulu wezinto emva kofakelo olupheleleyo. Inokwakheka kweconical kunye ne-conical groove phezulu. Injongo ye-countersunk hole kukudala indawo egudileyo kunye nefanayo emva kokuqinisa isikrufu. Xa i-countersunk screw ifakwe ngokupheleleyo, intloko iya kugungxulwa okanye ingaphantsi kancinane kumphezulu wezinto eziphathekayo, ifezekise ukubonakala okungenamthungo. Izikrufu ze-Countersunk zidla ngokusetyenziswa xa kufuneka indawo ethe tyaba kunye negudileyo, kwaye ziqhele ukusetyenziswa kwiplanga, iikhabhathi, kunye nezicelo ezibeka phambili ubuhle kunye nemigca ecocekileyo.
Kwelinye icala, iintloko ze-screw ezingenakubalwa azinayo imilo yeconical okanye i-concave top, enentloko evezwe ngokupheleleyo. Injongo yabo yoyilo ayikuko ukugungxulwa nomphezulu wezinto eziphathekayo. Ngokuchasene noko, zineentloko ezinkulu, ezisicaba, okanye ezijikelezayo ezisabonakala xa isikrufu siqinisiwe ngokupheleleyo. Xa inkangeleko ye-screw ayixhalabisi kwaye yamkelekile okanye iyimfuneko ukusebenzisa iintloko eziphumayo okanye eziphakanyisiweyo, iintloko ze-screw countersunk zidla ngokusetyenziswa. Ezi zikrufu ziqhele ukusetyenziswa kulwakhiwo, ukwenziwa kwesinyithi, kunye nosetyenziso olubeka phambili amandla, ukuqina, kunye nokusebenza ngaphezulu kobuhle.
