1. Ukunciphisa ubunzima kunye nokuthintela umhlwa: Beka phambili izikrufu ze-TC4 titanium alloy—eyona ndlela ilungileyo yokutshintsha iibhayisekile kunye neebhayisekile, kunye nokusebenza okugqwesileyo kokusetyenziswa ngaphandle ixesha elide kufutshane nolwandle. Qiniseka ukuba uyayilawula i-torque ngexesha lokuhlanganiswa, kwaye usebenzise i-anti-seize compound xa ubopha i-titanium kwi-titanium.
2. Ukusetyenziswa ngaphakathi ngokubanzi ngebhajethi encinci, apho kufuneka kuphela ukuthintela ukugqwala okusisiseko: Khetha intsimbi engagqwaliyo engama-304.
3. Ukuze uhlale usemanzini olwandle ixesha elide okanye kwiikhemikhali ezithambileyo: Beka phambili intsimbi engagqwaliyo engama-316.
4. Ukufakela izixhobo ngokubanzi ngaphandle kwemfuneko yokunciphisa ubunzima okanye ukumelana nokugqwala, kwaye apho ixabiso liphantsi liphambili: Izikrufu zentsimbi yekhabhoni zebanga lesi-8.8.

Phakathi kwezinto ezineenkcukacha ezifanayo, i-TC4 titanium alloy yeyona ilula kwaye idlula ezinye ngamandla athile, ukumelana nokugqwala kwetyuwa, kunye nokumelana nokudinwa; nangona kunjalo, ibiza kakhulu kwaye ineemfuno ezikhethekileyo zokuhlanganiswa. Intsimbi yekhabhoni inika ixabiso elifanelekileyo kodwa ayinamandla okugqwala. Intsimbi engagqwaliyo ye-316 inokumelana ngcono ne-chloride ions kune-304, kodwa inika ukunciphisa ubunzima okulinganiselweyo.

Izikrufu ze-TC4 titanium alloy zikhaphukhaphu kwaye zinamandla aphezulu; zinika ukumelana netyuwa kunye nokugqwala, azinamagnethi kwaye azikhathali nokudinwa, kwaye zinokufakwa i-anodized ukuze kufezekiswe iintlobo ngeentlobo zokugqitywa. Zifanelekile kwiinguqulelo zeebhayisekile kunye neebhayisekile, kunye nezixhobo zeenqwelo-moya ezichanekileyo. Iingxaki ziquka ixabiso eliphezulu, ubunzima be-matrix obuncinci, ukuthambekela kokuwelda okubandayo ngexesha lokuhlanganiswa kwe-titanium-to-titanium threaded, imfuneko ye-torque elawulwayo kunye ne-anti-seize compound ngexesha lokuhlanganiswa, kunye nokungafaneleki kwiindawo ezigqwala kakhulu ezifana nezo zibandakanya i-hydrofluoric acid okanye i-hydrochloric acid egxininisiweyo.
