standard hole การใช้

• The plates of Nunavut and Northwest Territories are shaped like a polar bear but bolt to the standard holes.
• A non-standard hole in the striker channel ensures sufficient water displacement if the weapon becomes completely flooded with water.
• For example, if a hole is to be drilled, if the designer specifies a standard hole size then it reduces the cost because the drill bits of unusual sizes are not readily available they have to be custom made.
