Izikrufu zamaplanga

Isikrufu somthi, esikwaziwa ngokuba sisikrufu somthi, siyafana nesikrufu somatshini, kodwa intambo yesikrufu ngumsonto okhethekileyo womthi, onokujijwa ngokuthe ngqo kwinxalenye yomthi (okanye inxalenye) ukudibanisa intsimbi (okanye engeyontsimbi) inxalenye. kunye nomngxuma owenziwe ngomthi.Olu hlobo loqhagamshelwano lukwanokuqhawuka.

Inzuzo ye-screw yokhuni kukuba inamandla okudibanisa ngaphezu kokubethelwa, kwaye inokususwa kwaye ithathelwe indawo, engonakalisi umphezulu womthi kwaye ilungele ukusetyenziswa.

 Iintlobo eziqhelekileyo zezikrufu zokhuni ziyintsimbi kunye nobhedu.Ngokutsho kwentloko yesikhonkwane, zinokwahlulwa zibe yintlobo yentloko ejikelezayo, uhlobo lwentloko yeflethi kunye nohlobo lwentloko ye-oval.Intloko yezikhonkwane inokohlulwa ibe yisikrufu esifakwe kwi-slotted kunye ne-cross slotted screw.Ngokuqhelekileyo, i-screw yentloko ejikelezileyo yenziwe ngentsimbi ethambileyo kwaye iluhlaza okwesibhakabhaka.Isikrufu sentloko esisicaba siyagudiswa.Isikrufu sentloko embhoxo sidla ngokufakwa i-cadmium kunye nechromium.Ihlala isetyenziselwa ukufaka iqabunga elivulekileyo, i-hook kunye nezinye izixhobo ze-hardware.Iimpawu zichongwa ngububanzi kunye nobude bentonga kunye nohlobo lwentloko yesikhonkwane.Ibhokisi yiyunithi yokuthenga.

 Kukho iindidi ezimbini ze-screwdrivers zokufakela izikrufu zomthi, enye ithe tye kwaye enye ingumnqamlezo, elungele imilo ye-groove yentloko yesikrufu somthi.Ukongezelela, kukho umqhubi okhethekileyo ofakwe kwi-bow drill, efanelekile ukulayisha kunye nokukhupha izikrini ezinkulu zokhuni.Iluncedo kwaye igcina umsebenzi.
