SS M6 round head bolts

    The characteristic of the semicircular head square neck Bolt is that the head is made into a semicircular ball, and a section of square neck is made under the head; It is mainly used in situations where hexagon Bolts are not suitable for the connected parts due to structural constraints or where the bolts are required to have smooth exposed parts.

    The Screw like the one in the picture below is what we often call a round-headed screw. There is a round shape similar to a gasket between the head of the screw and the screw. It is cold-headed together with the screw head. It is formed by machinery and equipment at once.

    Then why does this kind of round head screw appear? We know that the screw is screwed into the product as a connecting fastener. The screw head and the surface of the product generate mutual force to fasten the parts of the product. connect. If the contact area between the screw head and the product is small, the pressure will be large, and the surface of the product will be easily damaged. And the head area of this screw with intermediary is much larger than that of ordinary screw without intermediary, the larger the contact area with the product, the less likely to damage the surface of the product. This is why there is such a round head screw, which is designed to protect the product from damage.
