304 internal serrated lock washer Serrated washers are used as springs on small parts and are about the same size as the fastening screws and self-tapping screws used with them in three-dimensional sheet metal stampings.
304 stainless steel hexagonal slotted half thread thin shank bolt
Countersunk head tapping screws Countersunk head tapping screws and flat-tail nails are often used in the installation of electronic and electrical products.
Dacromet external hexagonal full thread bolts DIN 933-1987 Fanyi external hexagon bolts are surface treated with Dacromet. Dacromet is the transliteration of DACROMET in English, also known as Dacromet or Dacromet Rust. It is a new type of metal surface anti-corrosion coating that uses metal aluminum, zinc and chromic acid as the main coating materials. The base materials using Dacromet are mainly steel and non-ferrous metals. After the coating liquid reacts with the metal base, a silver-gray anti-corrosion film is formed on its surface, isolating the base from the air and protecting the workpiece. Dacromet is widely used in various industries, such as fasteners, construction, small hardware, road engineering and petrochemicals.
Dacromet surface treated hexagonal nuts The surface of the hexagonal nut is treated with Dacromet, which is the transliteration and abbreviation of DACROMET, also known as Dacromet, Dacromet, and Dicromet. Domestically, it is named zinc-chromium coating, which is a new type of anti-corrosion coating with zinc powder, aluminum powder, chromic acid and deionized water as the main components.
Equal length studs JB /T 4707 – 2000 Stainless steel 304 Standard number: JB /T 4707 – 2000 Studs are also called stud screws or stud bolts. They are used to connect machinery. Stud bolts have threads on both ends, and the screw in the middle can be thick or thin. They are generally used in mining machinery, bridges, automobiles, motorcycles, boiler steel structures, crane towers, large-span steel structures and large buildings.
Finexpress Dacromet Washer GB/T 95 The surface of the gasket is treated with Dacromet to have strong corrosion resistance and is mostly used in outdoor power towers and other equipment. Flat washers are usually thin pieces of various shapes, used to prevent leakage, reduce friction, prevent loosening, separation or disperse pressure. Many mechanical structures or installations have such parts, which are used to perform various similar functions. Due to the process and material limitations of threaded fasteners, the bearing surface of fasteners such as bolts is not large, so washers are used to reduce the compressive stress of the pressure-bearing surface and protect the surface of the connected parts.
Finexpress Hexagon Copper Nut Brass Material Copper nuts are mainly hexagonal nuts or other copper nuts that match bolts. Copper nuts have the advantages of anti-corrosion, easy heat conduction, strong electrical conductivity and not easy to rust. They are generally used in high temperature, electrical, thermal and rust-proof environments, such as electrical switches, faucets, valves, etc. Another main use of copper nuts is injection molding. After heating, they are directly molded or embedded into plastic parts. Brass has good thermal conductivity. If the copper nut is heated and then embedded, on the one hand, the heated copper nut can quickly transfer heat to the plastic part, and on the other hand, the copper nut can quickly heat up and speed up the work efficiency, thereby softening the periphery of the plastic hole, which is conducive to pressing into the hole.
Finexpress stainless steel round nut GB/T 812-1988 Generally, round nuts are used together with locking washers. When installing, the inner tongue of the washer is inserted into the groove on the shaft, and the outer tongue of the washer is embedded in the groove of the round nut. At this time, the nut is locked; or double nuts can be used to prevent loosening. It is often used as the axial fixation of rolling bearings. The thread specifications are round nuts with M10×1~M200×3.
Hexagon flange bolts Stainless steel flange bolts GB/T 16674.2-2016 Flange bolts are made up of a hexagonal head and a flange (the gasket under the hexagon is fixed together with the hexagon) and a screw (a cylinder with external threads). They need to be matched with nuts to fasten parts that connect two through holes….
Finexpress stainless steel blue-resistant 304 hexagon socket head half-thread screws GB/T 70-1985 The outer side of the screw head is a hexagonal shape with a round recess. This type of screw is called a hexagonal screw. A special wrench is needed to fix and remove this type of screw. Generally, special hexagonal wrenches are sold in hardware stores. The biggest function of a screw is to fix it, and the hexagonal screw is mainly used for mechanical fixation. The advantage of this is that it is easier to fix without the consequence of thread stripping. It is also easy to remove, which works with the hexagonal wrench.
12.9 Hexagon socket head screw Hexagon socket screws, also called hexagon socket bolts, cup head screws, hexagon socket screws, are called differently, but they mean the same thing. Commonly used hexagon socket head screws are also 4.8, 8.8, 10.9, and 12.9. They are also called hexagon socket screws and hexagon socket bolts. They have a hexagon socket head and a cylindrical head.
