strength.<br \/>\nThanks to these properties of the thread-rolled screw, we can state that it is no longer necessary to create long threads to ensure a better hold; indeed, it is thus possible to shorten them, saving die stroke and tap life.<br \/>\nThe following formula can be used to calculate the required thread depth:<\/p>\n<p><strong>h = 0.9 x D (thread \u00d8)<\/strong><\/p>\n<p><strong>LUBRIFICATION<\/strong><br \/>\nIn order to get the best tap life we suggest to use an Intercom specific oil for rolling tap.<\/p>\n<p><strong><br \/>\nFormulas for
