Metrik Harici \u0130\u015f Par\u00e7ac\u0131klar\u0131n\u0131 Anlamak<\/h2>\n

Metrik di\u015f sistemlerinde, d\u0131\u015f di\u015fler i\u00e7in ana \u00e7ap 'd', c\u0131vata veya vidalardaki di\u015f tepesinin en d\u0131\u015f \u00e7ap\u0131n\u0131 temsil eder. Bu boyut, ilgili i\u00e7 di\u015fle temas alan\u0131n\u0131 belirledi\u011fi i\u00e7in di\u015f mukavemeti ve uyumu a\u00e7\u0131s\u0131ndan temel \u00f6neme sahiptir. Nominal de\u011ferlerden sapmalar, yetersiz kavrama veya montaj s\u0131ras\u0131nda a\u015f\u0131nma gibi montaj hatalar\u0131na yol a\u00e7abilir.<\/p>\n

Metrik di\u015fler, nominal boyut (\u00f6rne\u011fin, M10), ad\u0131m ve tolerans s\u0131n\u0131f\u0131 ile belirtilir. Ana \u00e7ap tolerans\u0131, ISO 965-1'de tan\u0131mland\u0131\u011f\u0131 gibi, k\u00fcresel \u00fcretimde de\u011fi\u015ftirilebilirli\u011fi sa\u011flar. D\u0131\u015f di\u015fler i\u00e7in toleranslar genellikle negatiftir; yani ger\u00e7ek \u00e7ap, bo\u015fluk pay\u0131 sa\u011flamak i\u00e7in nominal \u00e7aptan daha k\u00fc\u00e7\u00fck veya ona e\u015fittir.
