Screw yog ib qho ntawm cov fasteners feem ntau, thiab muaj ntau hom screws, nrog rau cov laum tail screws thiab tus kheej tapping screws.
Tus Tsov tus tw ntawm lub laum tus Tsov tus tw yog nyob rau hauv cov duab ntawm ib tug laum tus Tsov tus tw los yog taw tes tus Tsov tus tw, thiab tsis yuav tsum tau auxiliary ua. Nws tuaj yeem ncaj qha drilled, tapped, thiab xauv rau ntawm qhov chaw thiab cov khoom siv hauv paus, txuag lub sijhawm tsim kho. Piv nrog rau cov ntsia hlau zoo tib yam, nws muaj lub zog tensile siab thiab tuav lub zog, thiab yuav tsis loosen txawm tias tom qab ua ke rau lub sijhawm ntev. Nws yog ib qho yooj yim los siv kev nyab xeeb drilling thiab tapping kom tiav cov haujlwm hauv ib qho mus. Tshwj xeeb tshaj yog nyob rau hauv kev koom ua ke ntawm kev tsim kho, architecture, vaj tse thiab lwm qhov chaw, tus kheej tapping thiab nws tus kheej drilling screws yog qhov zoo tshaj plaws kev lag luam fasteners nyob rau hauv cov nqe lus ntawm operability, nqi thiab kev cia siab rau.
Self tapping screws, tseem hu ua ceev ceev cov ntsia hlau, yog cov hlau fasteners uas tau undergone nto galvanization thiab passivation. Tus kheej tapping screws feem ntau yog siv rau kev sib txuas cov hlau nyias (xws li cov phaj hlau, saw phaj, thiab lwm yam). Thaum sib txuas, ua ntej ua ib lub qhov hauv qab rau qhov txuas, thiab tom qab ntawd ntsia hlau tus kheej tapping ntsia hlau rau hauv cov xov hauv qab ntawm qhov txuas.
① Distinguishing ntawm drilling tail screws thiab nws tus kheej tapping screws nyob rau hauv cov nqe lus ntawm cov ntaub ntawv: drilling tail screws belongs rau ib hom ntoo ntsia hlau, thaum tus kheej tapping screws yog ib hom ntawm nws tus kheej-locking ntsia hlau.
② Kev sib txawv ntawm qhov drilling tail screws thiab tus kheej tapping screws nyob rau hauv cov nqe lus ntawm lawv cov kev siv: Drilling tail screws yog tsuas yog siv rau kho cov xim hlau vuas thiab nyias daim hlau nyob rau hauv steel qauv. Lub ntsiab feature yog tias tus Tsov tus tw yog nyob rau hauv cov duab ntawm ib tug laum tail los yog taw tes tail. Thaum siv, tsis tas yuav muaj kev pabcuam ua haujlwm, thiab drilling, tapping, xauv, thiab lwm yam haujlwm tuaj yeem ua tiav ncaj qha ntawm cov khoom hauv ib qho, txuag lub sijhawm teeb tsa. Self tapping screws muaj siab hardness thiab kuj siv tau rau cov ntaub ntawv uas muaj hardness siab, xws li hlau daim hlau. Nws muaj qhov qis qis torque thiab kev ua haujlwm siab xauv.
③ Qhov sib txawv ntawm cov laum tail screws thiab nws tus kheej tapping screws nyob rau hauv cov nqe lus ntawm kev ua tau zoo: Laum tail screws yog cov cuab yeej siv lub cev thiab lej cov ntsiab lus ntawm inclined ncig rotation thiab kev sib txhuam ntawm cov khoom kom maj mam zawm cov khoom ntawm cov khoom. Drill Tail Screws yog cov ntsia hlau nrog tus kheej tapping laum lub taub hau ntawm qhov kawg ntawm lub hau. Tus kheej tapping screws feem ntau yog siv rau kev sib txuas cov hlau nyias (xws li cov phaj hlau, saw phaj, thiab lwm yam). Thaum sib txuas, ua ntej ua ib lub qhov hauv qab rau qhov txuas, thiab tom qab ntawd ntsia hlau tus kheej tapping ntsia hlau rau hauv cov xov hauv qab ntawm qhov txuas.
