Product description:
The screw is a tool for fastening the machine parts step by step by using the physics and mathematics principles of the circular rotation of the inclined plane and friction. Screw is a general term for fastener. Screws are indispensable industrial necessities in daily life: such as cameras, glasses, clocks, electronics, and so on the use of tiny screws; General screws for TV sets, electrical products, Musical Instruments, furniture, etc. As for engineering, construction, bridge use large screws, nuts; Transportation equipment, aircraft, tram, car and so on are both large and small screws. The screw plays an important role in industry. As long as industry exists on earth, the function of the screw will always be important.
Practical use:
it is mainly used for fixing tubular objects such as water pipes or sheet objects such as automobile plate spring construction installation, mechanical parts connection, vehicles, ships, Bridges, tunnels and railways, etc. Main shape: semicircle, square right Angle, triangle, oblique triangle and so on.
application fields
Suitable for concrete and dense natural stone, metal structure, metal profile, bottom plate, support plate, bracket, baluster, window, curtain wall, machine, girder, girder, bracket, etc.
The main uses of stud are:
1, in the main body of large equipment, need to install the accessories, such as sight glasses, mechanical seal, deceleration machine frame, etc., this is just use the stud, end turned into the main body, the other end with nut after installed accessories, because the attachment is often removed, thread will wear or damage, use the stud replacement will be very convenient.
2. When the thickness of the connecting body is very large and the length of the bolt is very long, the bolts will be used!
3, used to connect thick plate and inconvenient to use hexagonal bolt connection, such as concrete roof frame, roof beam hanging monorail beam hanging parts.
