I. Price
The price of stainless steel nails is generally 10 yuan 50 kg. Commonly used are semi-circular head, flat head, countersunk head stainless steel nail, core-pulling stainless steel nail, hollow stainless steel nail and semi-hollow stainless steel nail. These usually use their own deformation to connect riveted parts. (Generally, those smaller than 8 mm are riveted by cold riveting, and those larger than 8 mm are riveted by hot riveting ... But there are exceptions, such as the nameplate on the three-ring lock, which is riveted by the interference of stainless steel nails and lock body holes. In addition, stainless steel nails are inserted in pairs, which is quite special. It is divided into two parts. The center of the thicker section of the capped rod body has a hole, which is in interference fit with the thinner section of the capped rod body. When riveting, just drive the thin rod into the thick rod.
Two. Brief introduction of stainless steel nail
Stainless steel nail: In riveting, the riveted parts are connected by their own deformation or interference. There are many kinds of stainless steel nails, and they are irregular.
According to the stress form, stainless steel nails can be divided into three types: shear stainless steel nails, tensile stainless steel nails and shear stainless steel nails.
Third, use stainless steel nails.
Semi-circular head stainless steel nail: mainly used for riveting occasions with large lateral load, which is the most widely used.
Stainless steel nail with flat cone head: Because the nail head is large, it can resist corrosion and is often used in riveting occasions with strong corrosion such as hull and boiler water tank.
Countersunk stainless steel nail, 1200 countersunk stainless steel nail: mainly used for riveting occasions with smooth surface and little load.
Semi-countersunk head and 1200 semi-countersunk head stainless steel nails are mainly used for riveting occasions where the surface must be smooth and the load is not large.
Flat head stainless steel nail: used for riveting under general load.
Flat head and round head stainless steel nails: Flat head stainless steel nails are mainly used for riveting metal plates or non-metallic materials such as leather, canvas and wood. Large flat head stainless steel nails are mainly used for riveting nonmetallic materials.
Semi-hollow stainless steel nail: that is, the cylindrical part of the stainless steel nail is machined into a depression, which is mainly used for riveting occasions with small load.
The above is the price introduction of stainless steel nails. Stainless steel nail is a kind of nail that can be used to connect parts. There are still many kinds of nails, and the bearing capacity is the strongest among them, which can bear a relatively large load. Stainless steel nails are mainly used for some smooth walls and can be nailed to leather. Most of the nails used in electric appliances in our life are stainless steel nails. Stainless steel nails are not easy to oxidize and react chemically, and are the most widely used nails at present.
