Scriúnna teaglaim boltaí ceann heicseagán ard-neart le haghaidh struchtúir chruach, a úsáidtear go príomha i droichid iarnróid agus mhórbhealaigh, struchtúir choirí cruach, gléasraí tionsclaíocha, foirgnimh shibhialta ard-ardú, struchtúir túir agus crann, innealra ardaitheoirí agus a gcuid ní mór do struchtúir chruach úsáid a bhaint as frithchuimilt-cineál ard-teaglaim boltaí ard-neart le haghaidh scriúnna. Tá sé tréithrithe ag dodecagon breise ag deireadh an bolt, ar a dtugtar an bolt freisin. Nuair a shuiteáiltear, ní mór eochair leictreach speisialta a úsáid. Tá dhá cheann soicéad suas agus síos, tá ceann amháin socraithe ar chorp heicseagánach an chnó, agus tá an ceann eile socraithe ar chomhlacht decagon an scriú heicseagán seachtrach. Nuair a bhíonn tú ag géarú, cuir fórsa deiseal i bhfeidhm ar an gcnó, agus cuir fórsa cothrom tuathalach i bhfeidhm ar chorp dodecagon an bolt, ionas go mbeidh an nasc idir deireadh an scriú heicseagán seachtrach agus an comhlacht dodecagon faoi réir lomadh torsional go dtí go bhfuil an muineál. lomadh. Go dtí seo, tá an suiteáil críochnaithe. Scriú úsáide ama amháin is ea an scriú heicseagán seachtrach ard-neart seo agus go ginearálta ní féidir é a bhaint tar éis é a shuiteáil.

Is é seo an scriú teaglaim a thabhairt isteach agus a úsáid.
