Why Are The Bolts That Hold Steel Rails Together In Oval Holes? |
|
Answer» It has to do with the design of the bolts. The reason that head of the bolt is OVAL. The head of a bolt fit flush into the bar and set in opposing sets is so that a piece of DRAGGING equipment will not SHEAR off all the bolts in a joint but rather the just the nuts ONE side. As a result, if the hole were not oval on one side there would be no WAY to tighten or loose the bolts in a joint. It has to do with the design of the bolts. The reason that head of the bolt is oval.
