Omadused ja eelised
DIN 6921 on teatud tüüpi kuuskantäärikpoldid, mida kasutatakse tavaliselt tööstus- ja ehitusrakendustes.Sellel poldil on äärik, mis toimib sisseehitatud seibina ja aitab jaotada koormust laiemale pinnale.Poldi pea on kuusnurkse kujuga ja seda on lihtne mutrivõtme või pesa abil pingutada.
Seda polti kasutatakse selle erakordse tugevuse ja vastupidavuse tõttu laialdaselt masinates, autotööstuses ja ehituses.See on valmistatud kvaliteetsetest materjalidest, nagu roostevaba teras, titaan ja süsinikteras, mis tagavad pikaajalise kulumis-, korrosiooni- ja roostekindluse.
DIN 6921 poldid on valmistatud rangete tolerantside järgi ja nende suhtes kohaldatakse rangeid kvaliteedikontrolli meetmeid, et tagada nende vastavus kõrgeimatele kvaliteedi- ja jõudlusstandarditele.Need poldid on saadaval erineva suuruse, pikkuse ja viimistlusega, et need sobiksid erinevate rakenduste ja nõuetega.
Lisaks vastavad DIN 6921 poldid rangetele tööstusstandarditele, sealhulgas DIN (Deutsches Institut für Normung) ja ISO (Rahvusvaheline Standardiorganisatsioon) standarditele.Enne müügile laskmist testitakse ka nende kõvadust, tõmbetugevust ja mõõtmete täpsust.Kõik need tegurid aitavad kaasa DIN 6921 poldi suurepärasele kvaliteedile ja töökindlusele.
Üldiselt on DIN 6921 polt mitmekülgne ja vastupidav kinnituslahendus, mida kasutatakse paljudes erinevates tööstusharudes.See on loodud pakkuma suurepärast hoidejõudu, vastupidavust kulumisele ja paigaldamise lihtsusele.Selle kvaliteetne ehitus ja range järgimine tööstusstandarditele teevad sellest parima valiku inseneride, disainerite ja ehitusprofessionaalide jaoks kogu maailmas.
