Q:Is the tail screw? If it is mainly used in what place? If not what are they different?
This kind of screw called what I really do not know its name, the use of the place to see really not much, I see the place are generally used in machinery and equipment above, as you said what role, my personal point of view is To prevent slipping, because it is the head of a large slip wire, need to hand to adjust to the correct position to fall off, know that so much, not professional, Oh ~ hope to help you! The
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:How to use washer, gasket, o-ring "
Three are used to enhance the sealing performance of the accessories, in general:Washer gasket, a uniform thickness of the ring, used in the bolt to enhance the connection between the fastening; gasket gasket, a variety of shapes, for a variety of occasions, enhance the tightness. In general, both are metallic and washer is included in the category of gasket.Liner and O-ring are commonly referred to as sealing ring, rubber material, shaped like a mini version of the buoy, but the wall thickness is larger and better elasticity, mainly used for instrument installation in Glen head.
Q:No cross screwdriver, how can the screwdriver screwdriver?
Some nail holes have depth, you can use the female (black vintage kind) steel wire card flat steel filing with a file to repair a little more can be a little more, if the nail in the plane, The use will also be on the.

Today, many things are fixed with screws. Look around the house, the eyes see all kinds of things - from furniture to food processors, are connected with screws. The spirits were invented more than 2,000 years ago, but less than 500 years for fixing things.
Q:In the fastener industry, 1018 refers to what material
Low-carbon steel. Domestic in accordance with the Japanese standard to create the SWRCH18A. (JIS G 3507) Carbon C: 0.15 to 0.20 Silicon Si: 0.17 to 0.37 Mn Mn: 0.60 to 0.90 Phosphorus P: ≤0.030 Sulfur S: ≤0.035 The carbon content of the material is relatively low and can not be quenched and tempered. Used for cold piers to make low-grade screws. Pull up the strength of 450Mpa.
Q:I would like to ask what is the standard gasket and gasket in general what material?
Less dosage, the metal with Q235, rubber with XB200, are very common. If the amount is large, according to the situation to choose the most economical
Q:Why are the screws of the screw?
Fine thread thread pitch is small, the angle is small, self-locking is better, high strength, because the teeth are not wearable, easy to slip. Fine thread is often used in fine parts, thin-walled pipe fittings or by the impact, vibration and variable load connection, can also be used as fine-tuning mechanism for adjusting the thread.
Q:Gasket 300HV relative to what material?
Gasket 300HV relative to the usual selection of 45, 50, 60, 70 steel or 65Mn steel.
Q:what parts do Fasteners include
Bolts: A fastener consisting of a head and a screw (with an external thread), which is fitted with a nut for fastening the connection of two parts with through holes. This type of connection is bolted. If the nut is screwed off from the bolt, it is possible to separate the two parts, so the bolt connection is a detachable connection.
