    Hex bolt: A type of fastener consisting of a head and a screw (a cylinder with external threads), used in conjunction with a nut for fastening two parts with through-holes. This type of connection is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
    1. According to the force mode of connection, there are ordinary and reaming holes. Bolts for reaming holes should fit the size of the holes and be used when subjected to transverse forces.

    2, according to the head shape of hexagonal head, round head, square head, countersunk head, and so on, the general countersunk head is used in the requirements of the connection after the surface is smooth without protrusions, because the countersunk head can be screwed into the parts. Round heads can also be screwed into parts. The tightening force of square head can be larger, but the size is large. The hexagonal head is the most commonly used.

    Drywall screw with coarse thread and bugle head /  Drywall Screws with Fine Thread        

    Dry wall nail is a kind of nail, the biggest characteristic in appearance is horn head shape, divided into double fine tooth dry wall screw and single thick tooth dry wall screw, the biggest difference between the two is that the thread of the former is double thread.Drywall screw series is one of the most important fastener products. The product is mainly used for the installation of various gypsum board, light partition wall and ceiling ceiling series

    Phosphating dry-wall screw is the most basic product line, and blue and white zinc dry-wall screw is a supplement, the scope of application and purchase price of the two are basically the same. Slightly different is that black phosphating has a certain lubricity, attack speed (into the speed of the specified thickness of the steel plate, is a quality assessment index) slightly better; Blue and white zinc in the rust effect is a little better, and the color of the product is shallow, not easy to color after coating decoration.

    There is almost no difference between blue and white zinc and yellow zinc in rust resistance, only the difference in use habits or user preferences.

    DIN7981 DIN7982 DIN7983 Screw Flat Head Pan Head Self Tapping Screw teel Zinc Plated Self Tapping Screw/Self Drilling Screw Chipboard Screw/Hex Head Screw/Pan Head Screw

    Generally, it is the wood screw with fingertip head, thick teeth and hard texture, as well as aluminum alloy and plastic. A special type of self-tapping screw used to open threads in metal holes is called a tap.

    Self tapping screws for non-metal or soft metal, do not need to hit the bottom hole and tapping; Self tapping screws are pointed, so as to “self tapping”; Ordinary screws are flat – headed and of the same thickness.

    Self tapping screw is to say: drill holes without tapping holes, the screw and the general difference, the head is pointed, the tooth distance is relatively large, and the chip free wire tapping is a bit like, can not tap directly screw in, metal and plastic usually use this method.

    It can be consolidated on the material, relying on its own thread, will be consolidated body “tap – drill, squeeze, pressure” out of the corresponding thread, so that it closely with each other
