Description:
Carriage bolts which is also called round head square neck screws, mushroom head square neck screws, and coach bolt.
Generally speaking, bolts are used to connect two objects, usually through the aperture. And it needs and nut to use. It can not afford to action single. General tool is a wrench. Head is mostly hexagonal, generally larger. Usually do not need screw nut, cooperating directly with the two objects (general connection must first drilling, tapping), generally with a screwdriver tool (screwdriver), mostly slotted head, cross slot, hexagonal inside and outside a lot, generally small.
Carriage bolts were developed for use through iron strengthening plates on either side of a wooden beam. It is commonplace though to use them to bare timber, the squared section giving enough grip to prevent rotation.
Carriage bolts are extensively used in security fixings, such as the Brenton Bolt where the bolt must only be removable from one side. The smooth domed head and square nut below prevent the carriage bolt from being unlocked from the insecure side
