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

Carbon Steel Grade 8.8 Grade10.9 Hexagon Hex Head Bolt DIN931/ISO4014 Carbon Steel Hexagon Head Flange Bolt
Bolt: Machine part, cylindrical threaded fastener with nut. A type of fastener consisting of a head and a screw (a cylinder with external threads) that is fitted 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.
According to the thread tooth type is divided into coarse teeth and fine teeth two categories, coarse teeth in the bolt logo does not show. Bolts are divided into grades 4.8, 8.8, 10.9 and 12.9 according to the performance grade. Bolts above 8.8 (including 8.8) are made of low-carbon alloy steel or medium carbon steel and treated with heat treatment (quenching and tempering), generally known as high strength bolts, and bolts below 8.8 (excluding 8.8) are generally known as ordinary bolts
