Heat resistance refers to both the oxidation resistance or gas medium corrosion resistance at high temperature, that is, thermal stability, and at the same time, it has sufficient strength at high temperature, that is, thermal strength. As the material requirements of products produced by customers are getting higher and higher, the requirements for screws used in product materials are also getting higher and higher. When product materials face harsh environments and special occasions, more and more high-quality mechanical properties of stainless steel screws are used. Therefore, stainless steel screws were selected. The requirements are getting higher and higher, and the material of stainless steel screws is getting higher and higher. Therefore, many ordinary stainless steel screws SUS201 are replaced by stainless steel SUS304 screws and stainless steel screws SUS316. Of course, if some requirements are not so high, general customers will choose stainless steel screws SUS201, which are relatively cheap in cost.
The two combination screws are classified according to the national standard, including GB9074.2, GB9074.3, GB9074.5, etc. GB9074.3 refers to a two-component combination of a cross pan head screw and a foreign lock washer.
Pressure riveting standoffs, also known as pressure riveting studs or standoffs, are non-removable fasteners that are used in conjunction with rivets to provide a threadless type. A sheet metal part is a product processed by a sheet metal process, that is, a sheet metal substrate is formed into a sheet metal part with a certain shape through cutting, bending, drilling, welding and other processes. On some sheet metal parts, such as chassis and electrical boxes produced by sheet metal, it is usually necessary to set rivet standoffs to facilitate the installation of internal components. The existing standoffs are usually installed on the sheet metal substrate by extrusion, and the connection is not firm.
In real life, rivet nuts are used. With different specifications and different uses, many people are familiar with this tool but don't know how to use it properly. In fact, rivet nut tools have manual and transmission, and now are rarely used for manual. If you choose to use electric rivet nuts in order to improve production efficiency, which of the two is more widely used? The following describes the use of electric rivet nuts and manual nuts. How to use the manual rivet nut tool: Insert the rivet nut into the drilled installation hole with a rivet mother tool to fix the rivet nut. (1) Screw the rivet nut onto the rivet nut tool 2) Use the rivet nut tool to insert the rivet nut into the drilled mounting hole. (3) Tighten the nut, and press the handles on both sides of the rivet nut tool to the direction of the middle round rod. You can only press it hard. Therefore, this pressure must be in place. It is forbidden to repeatedly squeeze the handles on both sides to damage the nut. Fastening thread in the form of inside. (4) The rivet nut tool is separated from the rivet nut: just loosen the ball head in the picture, and the tool will be separated from the nut after completely loosening.
