Wood Products Industry-1

The screws are popular used for wooden industry, commercial construction,household appliances, electronic products, mechanical products, digital products, electric equipment,electromechanical machinery products.Ship, vehicles, water conservancy projects etc.    

Screws are indispensable industrial necessities in daily life: such as washing machines, refrigerators, hoods, home speakers, musical instruments, furniture, etc.; as for engineering, architecture, and bridges Aircraft, trams, cars, etc. are used with screws. Screws have important tasks in industry. As long as there is industry on the earth, the function of the screw is always important. The role of the screw is mainly to connect the two work pieces together to play a tight effect.

Screws are generally called wooden screws. It is the kind of pointed at the front end. The splitter distance is large. It is generally used for firming wooden parts and plastic parts. The screw rod is a machine screw (mechanical screw), which is the kind of flat head. The screw is small and uniform. It is generally used for firing metal and machine components.

The wood screw is similar to the machine screw, but the thread on the screw is a special wood screw thread, which can be directly spin into the wooden component ( or parts ) to use it to put a metal ( or non-metal ) part with a pore with a wooden parts with a wooden part. The component is tightly connected. This connection is also a disassembly connection.

Several common screws:

Self-tapping screws, or fast teeth screws, is a fast-paired fastener with galvanized passivation of steel on the surface of the steel. Self-tapping screws are mostly used between thin metal plates ( steel plates, sawdors, etc. ). When the connection is connected, first make the thread bottom holes out of the connector, and then the self-tapping screw is twisted into the thread bottom hole of the connector.

Self-tapping lock screws are mostly used for the connection between thin metal plates. Its thread is an ordinary thread with a curved triangle section, and the surface of the thread also has high hardness. Therefore,during connection, the screw can also tap the inner thread in the threaded bottom of the connector to form a connection. The characteristics of this screw are characterized by low twisting torque and high locking performance, which has better working performance than ordinary self-tapping screws, and can be used instead of machine screws.

Self-tapping screws of the wall plate are used for connection between gypsum wall boards and metal keel. Its threads are double-headed threads, and the surface of the thread also has high hardness( ≥ HRC53 ). It can quickly screw into the keel under the condition that the prefabricated hole is not produced to form a connection.  

Self-drilling screws are different from ordinary self-tapping screws. When ordinary self-tapping screws are connected, they must pass through the two processes of drilling ( drilling thread bottom ) and tap wire ( including tight connection ); About self-drill, when the screw is connected, the drilling and tap wire are combined to complete it once. It first uses the drill in front of the screw to drill, and then use screws to tap ( including fastening connection ) to save construction time and improve construction efficiency.

Self-drilling screws of the plate head and hexagonal head are suitable for the occasions that the drills are allowed to be exposed. The hexagonal self-drilling screw is compared to the big torque of the Pan head self-drilling screw. The sediment and the inner hexagonal self-drilling screws are suitable for the occasion that the nail head is not allowed. A occasion. During the disassembly of the self-drilling screw, the slot self-drilling screws need to be rotated with one-shaped screws. Attack screws need to be a stubborn wrench, plum wrench, sleeve wrench or live wrench.

Dovetail screw

Generally, dovetail screw does not require auxiliary processing. You can directly drill a hole in the object directly on the object. Not only is it very convenient to use, it can greatly improve the efficiency of work. This dovetail screw can be said to be the first choice of staff in various fields.  

The use of screws is widely used for different application and the screw market is large, leading to more suppliers. When choosing a professional screw supplier, the purchaser needs to understand some of the professional basic knowledge of the screws.
