We can modify the dimension and do some special screw end machine working acorrding our customer's request

Q:How much is a screw?: Let me tell you: a box of screws 500 yuan, a box of 600, how to calculate how much money? Fasteners consultants Yu Wenlong that a box of screws are the same standard, the same specifications, the same material screws, A 500600 = 083 yuan, about each is 083 yuan,

Q:No cross screwdriver, how can the screwdriver screwdriver?: If the head of the screw is fully exposed, use a large pliers to tighten the screw head from the side and turn the screw to the right.

Q:How is the screw produced: Annealing: the wire heated to the appropriate temperature, to maintain a certain time, and then slowly cooling to adjust the crystal structure, reduce hardness, improve the room temperature processing. Pickling: Remove the oxide film on the surface of the wire and form a layer of phosphate film on the metal surface to reduce the wire drawing and cold pier or forming process. To the required diameter. Practical for some products can be divided into coarse pumping (shelling) and fine pumping two stages. Molding: The wire is forged by cold forging (or hot forging) to achieve the shape and length (or thickness) of the finished product. The finished semi - finished product is rolled or tapped to achieve the desired thread. Practical for the bolt (screw) known as the rolling teeth, teeth known as the rolling teeth, nuts called tapping. Heat treatment: according to the object and the purpose of different different heat treatment can be used. Quenched and tempered steel: quenched high temperature tempering (500-650 ℃) spring steel: quenched after tempering temperature (420-520 ℃) ??carburizing steel: carburizing after quenching and then low temperature tempering (150-250 ℃) low carbon and In the carbon (alloy) steel quenched into martensite, with the tempered temperature rise, the general rule is the strength decreased, while the plasticity, toughness rise. Surface treatment: surface treatment that is through a certain method in the workpiece surface coating process, the purpose is to give the product surface appearance, anti-corrosion effect.

Q:Why the screw thread more closely, spin into the more effort?: Screw thread more dense, indicating the screw thread deep and shallow, the screw in the advance the resistance of the smaller, when the spin naturally more effort.

Q:Engineering argument, usually referred to as the M3 screw, M refers to what is the meaning? The Please instruct the engineering staff.: M is the large diameter of the screw, the diameter of the screw top of the bolt, or the diameter of the screw bottom of the nut

Q:I would like to know the specifications of the two types of screws models, including length, diameter, diameter and pitch, etc.: M3 means that the large diameter (external thread is the outer diameter) is 3. Of course with M3 nut, the length of a move does not include the nut. Thread section length is also another specification. M6 indicates a nominal diameter of 6 mm and indicates that it is a standard pitch coarse thread.

Q:What is the principle of screw: A simple mechanical one that can be used to overcome the difficulty of vertically lifting heavy objects. Distance ratio and force ratio are dependent on the inclination. Such as friction is very small, you can achieve very high efficiency

Q:What is the difference between Chinese-made screws and US screws?: China-made screws and the United States is no essential difference between the screws, and now the world are using the screws in China.

Q:Why should the screw twist clockwise?: Because the screw on the original flute is the clockwise direction of it

Q:How does the screw twist?: A kind of screw loosening agent, you can try. If it is slippery wire, and sub-specific circumstances, and sometimes can be destroyed by the screw head.
