5.10.1 Selectionofasuitablefastener
Ifafasteninghastobeperfectlysatisfactoryandreliableforitsentireservicelife,
allsurroundingconditionsmustbeascertainedbeforeasuitablefastenercanbe
selected.
Therefore,itisnecessarytotakeintoaccountwherethepartsareinstalled,indoor
oroutdoor.Foroutdoorapplications,adistinctionismadebetweenrural,urban,
industrialandmarineatmospheres.Nevertheless,therearespecialapplicationslike
wastewatertreatmentplants,industrialinstallations,roadtunnelsandswimming
pools.Inviewofthis,eachapplicationmustbeevaluatedseparatelyandthe
ndingsmustbeconsideredwhenselectingamaterialwiththerequiredcorrosion
behaviororasystemthatprovidesadequatecorrosionprotection.
Whenmaterialcombinationsareused,anevaluationoftheirelectrochemical
behaviorhastobeperformedtoavoidcontactcorrosion.
Notes
•Theinformationinthefollowingsectionmaybeofassistanceasitprovidessome
importantpointsthataidselection.Thetable,however,cannotcoverallindividual
aspects for each application.
•Theultimatedecisionontherequiredcorrosionprotectionmustbemadebythe
customer.Hiltiacceptsnoresponsibilityregardingthesuitabilityofaproductfora
specicapplication,evenifinformedoftheapplicationconditions.Thetablesare
basedonanaverageservicelifefortypicalapplications.Formetalliccoatings,
e.g.zinclayersystems,theendoflifetimeisthepointatwhichredrustisvisible
overalargefractionoftheproductandwidespreadstructuraldeteriorationcan
occur–theinitialonsetofrustmayoccursooner.
