Hex Head Self Drilling Screw

Izi ndi zomangira zomangira matailosi amtundu wachitsulo. Iwo ali m'gulu la self-tapping screws. Nthawi zambiri, mitu yawo imabwera mosiyanasiyana monga hexagonal ndi cross - recessed. Mchira wa screw rod ndi wakuthwa ndi ulusi, ndipo ena amakhala ndi chosindikizira chosindikizira pansi pamutu, chomwe chingapangitse kuti madzi asagwire ntchito. Nthawi zambiri amapangidwa ndi zitsulo za carbon ndi mankhwala opangira malata kapena zitsulo zosapanga dzimbiri, zomwe zimapereka dzimbiri zabwino - kupewa ndi kuwononga - kukana mphamvu.

Iwo makamaka ntchito unsembe ndi fixation mtundu zitsulo matailosi madenga ndi makoma. Amatha kubowola mwachindunji ndikumangirira muzitsulo zazitsulo ngati mbale zachitsulo zamitundu. Kuphatikiza apo, zimagwiranso ntchito pakulumikizana kwa kuwala - gauge zitsulo keels ndi zina zomanga nyumba.

Choyamba, kudziwa unsembe udindo pa mtundu zitsulo matailosi kapena zogwirizana zitsulo zakuthupi. Kenako, gwiritsani ntchito chida choyenera chamagetsi (monga chobowola chopanda zingwe) chokhala ndi pang'ono chomwe chimagwirizana ndi mtundu wa screw mutu. Gwirizanitsani wononga ndi malo omwe mwatsimikiza kale, yambani chida chamagetsi, ndikuyendetsa pang'onopang'ono wonongazo. Zodzibowola nsonga zidzalowa muzinthuzo pamene ulusi umalowa pang'onopang'ono, ndikukwaniritsa kukhazikika.
