One distinct feature of Bolt is that this fastener has to be used with Nuts. Bolts and Nuts always go together to form a strong cohesion. 


The head of bolt tends to have the shape of a hexagon or a circle. While hexagon head is a feature exclusive to bolts, circle head is characteristic of many types of fasteners. Therefore, if a fastener is hexagon headed, it is certainly a bolt. A bolt can also be headless. 

Two most common features of screws are head and threads.


In general, screws need to be used with pre-formed internal thread. There is another type of screw, however, that is called self-tapping screw. As the name indicates, self-tapping screw will form its own thread as it is being tapped in a pre-drilled hole . 

Vinh Vien company has the expertise and machinery to manufacture any machine parts according to customers’ blueprints or specifications.
