What is the tolerance range of precision screws?
At present, when fastening parts on thin-walled products or thin plates in our country, screws are usually used to fasten, and welding nuts are required to make the thin plate easy to burn through, or the objects are drilled and tapped to connect, so that the product is deformed and the connection strength is not strong. , It cannot be fastened on some equipment, the operation is inconvenient, and the production efficiency is low.
When using, after installing the nut and the bolt in place, insert the locking strip from the groove of the bolt, and make the V-shaped locking teeth of the locking strip snap into one of the V-shaped tooth grooves, and push the locking strip into the groove as a whole. The V-shaped locking teeth are stuck in the nut, and the locking strip body is stuck in the groove of the bolt, thereby restricting the relative rotation of the nut and the bolt, and there are threads between the nut and the bolt to restrict their relative sliding, so it can prevent the nut from loosening, even from The bolt falls off; when the nut needs to be disassembled, it is only necessary to pull out the locking strip from the groove, and the nut can be disassembled normally.
Spring washers are often called spring washers in the screw industry. Its materials are stainless steel and carbon steel, and carbon steel is also iron. The commonly used spring washers are M3, M4, M5, M6, M8, M10, M12, M14, M16. These specifications are more commonly used. The national standard for spring washers is GB/T 94.1-87, which specifies standard spring washers with a size of 2-48mm. Reference standard GB94.4-85 Elastic Washer Technical Conditions Spring Washer
Riveting is a method for combining two pieces of metal. Therefore, riveting technology is often used to fasten rivets such as nuts or rivets to metal sheets.
