Iziheavy duty konkire screw nangulandi zinc yokutidwa kapena galvanizedwithhex flange mutu. Ndi yosavuta kukhazikitsa, yosavuta kuzindikira ndi zochotseka kwathunthu. Ulusi wachitsulo womwe uli m'mbali mwa nangula umalowa mu dzenje pakuyikapo kuti upereke chinkhoswe. Zida zoyambira zoyenera zikuphatikiza konkire yolemera wamba, konkire yopepuka yamchenga, konkriti pamwamba pa chitsulo, miyala ya konkire ndi njerwa zadongo zolimba. Amagwiritsidwa ntchito kuyika konkriti, njerwa ndi midadada. Concrete Screw ndi yabwino kumangirira mu Njerwa Zapayekha. Amapanga ulusi muzinthu zomwe zimathandiza kuti bolt ichotsedwe popanda kuwononga dzenje. Kupaka kokhala ndi malata ndikoyenera kugwiritsidwa ntchito panja nthawi zambiri pamene zokutira za zinc galvanize ndizoyenera ntchito zambiri zamkati.
