Tek Screws Tus Kheej Tapping

Lub Tek screws tus kheej tapping, tseem hu ua tus kheej -drilling screws, feature ib tug xyaum taw tes taw tes uas tshem tawm qhov yuav tsum tau rau ib tug pre-drilled pilot qhov nyob rau hauv daim ntawv hlau thiab lwm yam ntaub ntawv. Los ntawm kev sib txuas cov drilling thiab tapping rau hauv ib qho kev lag luam, cov khoom lag luam no ua kom yooj yim rau kev sib dhos ua haujlwm hauv cov khw muag khoom tsheb, hlau vov tsev, HVAC ductwork, thiab hluav taws xob vaj huam sib luag tsim. Lawv yog lub hauv paus rau kev ua tau zoo, tus nqi- ua tau zoo hauv cov ntawv hlau sib dhos.

Lub ntsiab lus ntawm Tek screws nws tus kheej tapping yog nws qhov xyaum taw tes, muaj nyob rau hauv ntau qhov ntev (piv txwv li, # 2, # 3, # 5) kom nkag mus rau cov khoom sib txawv. Cov ntsia hlau shank muaj tapping threads uas ua raws li qhov xyaum taw tes los tsim mating threads. Lawv feem ntau yog tsim los rau fastening lub teeb rau nruab nrab gauge steel, aluminium, thiab lwm yam hlau rau hlau, muab cov pob qij txha muaj zog, txhim khu kev qha.

Peb Tek screws tus kheej tapping yog tsim raws li cov qauv kev lag luam, kom ntseeg tau tias muaj kev ntseeg siab ntawm qhov tawv thiab xov lub zog. Lawv feem ntau yog ua los ntawm cov hlau tsis muaj zog, feem ntau nrog cov phosphate lossis zinc -plated tiav rau corrosion kuj thiab du. Peb kuj muab cov hlau tsis muaj steel (A2) hloov pauv rau sab nrauv lossis corrosive daim ntaub ntawv. Lub taub hau hex ntxhua khaub ncaws lossis Phillips tsav yog qhov zoo, tso cai rau siab - torque installation nrog cov cuab yeej hluav taws xob txheem.
