3. Corrosion kuj. Yog tias tus kheej tapping screws siv nyob rau sab nraum zoov, qhov no yuav tsum tau siv tus kheej tapping screws kom muaj zog corrosion kuj.
4. High deg hardness thiab zoo core toughness.
5. Qhov ntau threads ib nti, lub zog ntawm tus kheej tapping muaj peev xwm ntawm cov ntsia hlau.
6. Nws lub peev xwm nkag mus feem ntau tsis tshaj 6mm, thiab qhov siab tshaj plaws tsis tshaj 12mm. Nws yog qhov tsim nyog rau kev kho cov phaj nyias, xws li txuas cov kab teeb ci ntsa iab, txuas xim hlau daim hlau thiab purlins, thiab lwm yam.
Qhov twg siv tus kheej tapping screws?
Raws li tau hais ua ntej,self-tapping screwsfeem ntau yog siv los kho cov ntoo boards, thiab tus kheej tapping screws kuj feem ntau siv rau kev teeb tsa ntawm lub qhov rooj thiab qhov rais. Tsis tas li ntawd, qee yam ntawm tus kheej tapping screws muaj cov sijhawm sib txawv.
1. Xov-forming screws. Nws yog tus cwj pwm los ntawm cov ntsia hlau qis-hauv torque thiab muaj zog xauv kev ua haujlwm. Nws muaj kev ua haujlwm zoo dua li qhov qub-tapping screws. Nws kuj tseem tuaj yeem hloov lub tshuab screws thiab feem ntau yog siv los txuas cov hlau nyias.
2. Drywall screws. Ib hom tshwj xeeb ntawm cov ntsia hlau tsim tshwj xeeb rau kev txuas cov phab ntsa ntub dej (tseem hu ua gypsum board lossis wallboard) rau cov ntoo lossis hlau. Lawv tau siv dav hauv kev tsim kho thiab kev txhim kho hauv tsev vim lawv lub zog, kev siv yooj yim, thiab kev ntseeg tau.
3. Self-tapping screws nrog ntau hom taub hau. Lub sijhawm siv tau ntawm cov ntsia hlau nrog lub taub hau sib txawv yog cuam tshuam nrog lawv lub taub hau hom. Piv txwv li, lub taub hau lub taub hau thiab hexagon taub hau tapping screws feem ntau yog siv rau hauv cov xwm txheej uas lub taub hau raug tso cai kom raug; countersunk taub hau screws yog qhov tsim nyog rau kev ua haujlwm countersunk kom ua rau saum npoo ntawm cov khoom sib txuas du thiab zoo nkauj.
