DIN 125 is produced very precisely and smoothly, while ISO 7091 is produced with coarser tolerances. The bore and OD of ISO 7091 is slightly more variable than DIN 125, which makes it more economical.<\/p><\/div>\n\n\n\n<div class=\"wp-block-safirtema-sorucevap safir-faq\"><div class=\"question\"><div class=\"icon\"><\/div><span class=\"text\">Why is Hot Dip Galvanizing (HDG) often preferred?<\/span><div class=\"openclose plus\"><\/div><\/div><p class=\"answer\">The hot-dip galvanized coating is thick. Precision washers have a narrow hole and the bolt may not pass through when galvanized. Since the hole tolerance of ISO 7091 washers is wider, the bolt passes through easily even with a thick galvanized coating. It speeds up assembly.<\/p><\/div>\n\n\n\n<div class=\"wp-block-safirtema-sorucevap safir-faq\"><div class=\"question\"><div class=\"icon\"><\/div><span class=\"text\">Which side of the washer should I install facing the bolt? <\/span><div class=\"openclose plus\"><\/div><\/div><p class=\"answer\">Although not a mandatory rule, one side of the washer is slightly rounded due to the punch entry and the other side is sharp. It is best to mount with the rounded side facing the bolt head and the sharp side facing the material.<\/p><\/div>","protected":false},"excerpt":{"rendered":"<p>ISO 7091, DIN 125 pullar ile benzer boyutlara sahip olsa da, en temel fark\u0131 \u00fcretim toleranslar\u0131n\u0131n daha geni\u015f ve y\u00fczey hassasiyetinin daha kaba olmas\u0131d\u0131r.
