Service HotlineGuangdong Yueluo Hardware Industry Co., Ltd. relates to a rivet nut fastener, which includes a body, and the rivet part of the body extends into the product to be processed. It is characterized in that trapezoidal teeth are formed on the joint surface of the body and the product to be processed. Or triangular teeth, there is a circular groove below it, and the height of the riveting part is 0.5-1mm smaller than the thickness of the processed product. Guangdong Yueluo Hardware Industry Co., Ltd. is suitable for riveting of any sheet metal materials, such as carbon steel plate, copper plate, aluminum plate, stainless steel plate, aluminum alloy plate, etc. Solid, high riveting surface flatness, providing good electrical contact performance.
The screw is a fairly common structure in the technical field of machine parts assembly, and it mainly uses the mutual engagement characteristics of male and female threads to achieve the purpose of pressing the workpiece. At present, there are many kinds of screws on the market, and their functions are also very different. However, a stud and a rotating part by which the stud is rotated are the same basic structure.
concealed screw fastener includes a washer, a screw and a shield, one end of the screw is provided with an end cap, the screw penetrates the washer and the end cap is supported on the washer, and the shield covers the end of the screw The cap is peripheral and connected to the gasket. When in use, firstly pass the screw through the washer and then drive it into the screw hole of the connected piece, and then cover the shield on the outer circumference of the end cap of the screw and connect it with the washer.
As a standard part, it should have its own general specifications. For hexagonal nuts, the commonly used standards are: GB52, GB6170, GB6172 and DIN934. The main differences between them are: GB6170 is thicker than GB52, GB6172 and DIN934. Thick from DIN934, commonly known as thick nut. The other is the difference between the opposite sides, the opposite sides of DIN934, GB6170 and GB6172 in the M8 nut series are 13MM smaller than the opposite side 14MM of GB52, and the opposite sides of M10 nuts, DIN934 and GB52 are 17MM. The opposite side of GB6170 and GB6172 should be 1MM larger, M12 nut, DIN934, GB52's opposite side is 19MM larger than GB6170 and GB6172's opposite side 18MM is 1MM larger. For M14 nuts, the opposite side of DIN934 and GB52 is 22MM, which is 1MM larger than the opposite side of GB6170 and GB6172, which is 21MM. The other is the M22 nut. The opposite side of DIN934 and GB52 is 32MM, which is 2MM smaller than the opposite side of GB6170 and GB6172, which is 34MM. (Besides the thickness of GB6170 and GB6172 are the same, the width of the opposite side is exactly the same) The rest of the specifications can be used in general without considering the thickness.
Screw: A type of fastener consisting of a screw head and a screw rod (a cylinder with an external thread), which needs to be used in conjunction with a nut to fasten and connect two parts with through holes. and widely used in people's lives. In real life, due to the vibration of the machine, the workpiece is loose at the connection between the screw and the nut, and the nut needs to be tightened frequently, which is time-consuming and laborious, delays time, and reduces the production efficiency, so how to reduce the production process. Frequent tightening of screws has become an unsolved problem for people. Therefore, there is an urgent need to provide a slotted screw.
