No tratmnts such as T-Washing or Etching can b appli bfor installation as this will chang th tightning charactristics an prvnt th corrct prloa bing achiv. Th componnts of th assmbly, as suppli, hav bn tst as a batch an must not b mix with componnts from any othr batch of HRC assmblis. Car must always b takn to avoi any contamination of th assmblis with anything that may chang th lubrication of th nut, bolt thra or washr. SUCH CONTAMINATION WILL EFFECT THE ASSEMBLY PRELOAD THAT IS ACHIEVED DURING TIGHTENING. Although HRC assmblis ar sign to withstan th maximum prloas that can occur whn contaminat with watr, w woul avis that tightning of HRC assmblis is avoi in th rain. 4 Stockists of Inustrial Fastnrs, Enginring Supplis an Halth & Safty Proucts
