Dacromet wani tsari ne wanda ba na lantarki ba wanda ke kawar da wannan haɗari gaba ɗaya, yana sa ya dace musamman ga ƙwanƙwasa masu ƙarfi.
• Kyakkyawan yanayin zafi da juriya na yanayi: Rufin ya kasance barga don amfani na dogon lokaci a kusa da 250 ° C kuma yana iya jure yanayin zafi na ɗan gajeren lokaci. Hakanan yana nuna juriya mai ƙarfi ga hasken ultraviolet da zazzagewar zafi mai ɗanɗano, yana tabbatar da ingantaccen aikin rigakafin lalata da tsatsa.
• Warkar da kai da kariya ta cathodic: Lokacin da rufin ya lalace a cikin gida, zinc da flakes na aluminum suna aiki azaman anodes na hadaya, suna ba da kariya ta electrochemical ga abin da aka fallasa da kuma haɓaka gabaɗayan anti-lalata da tsatsa- rigakafin iyawa.

3. Siffofin Tsari na Countersunk Hex Socket Bolts

Countersunk hex soket bolts (kuma aka sani da flat-head hex socket screws) yana da ƙira mai ƙira ko cylindrical countersunk. Bayan shigarwa, shugaban yana zaune gabaɗaya a cikin juzu'i a cikin countersink na kayan aikin, yana samun santsi, ƙasa mara ƙarfi. Na'urar hex na ciki yana tsakiyar tsakiyar kai, yana ba da damar ƙarfafawa mai inganci da cirewa tare da maɓallin hex yayin rage haɗarin zamewa.
