Service HotlineThe purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to overcome the deficiencies in the existing technology and provide a square nut fastener for cable tray installation, which has a simple and reasonable structure, and is extremely convenient and flexible to operate; it does not occupy C-shaped steel after installation. The space at the bottom increases the diversity of installation, and can be applied to square nuts of different thicknesses, and the installation is firm
At present, the commonly used locking structure is a split pin (hereinafter referred to as a cotter pin type adjustment nut) or knocking the sheet on the adjustment nut into the steering knuckle groove (hereinafter referred to as a sheet type adjustment nut), these two structures are mainly used in single row Bearings are barely used in bearing units and hub bearing units. The former has a complicated structure and the cotter pin is easy to fall off; the latter requires workers to control the press-in force. Too much pressure can easily lead to the cracking of the sheet structure on the adjusting nut, and too little pressure can easily make the adjusting nut failure, and is impacted in the axial direction.
Rivet nuts are mostly used in some chassis cabinets, square tubes and round tubes, fan production, equipment production, and zinc steel guardrails. Next, let’s talk about rivet nuts. The rivet nuts are also used on the top of the chassis cabinet sheet to provide threads. Its mode of operation is to use a riveting machine for riveting. In this case, the requirements will be higher, and a riveting machine is required. After the pressure riveting nut is riveted to the upper side of the sheet, it is very flat and will not have protrusions. Pressure riveting nuts are mainly used in the production of some chassis and cabinets, as well as some equipment production, water pumps, automobiles, and other production enterprises.
In terms of inner hexagon, there are two versions of the national standard, one is GB70-76, the 76-year version, and the other is GB70-85, the 85-year version, most of which implement the DIN912 standard, so you should pay attention to the difference in actual business operations: GB70 -85 completely coincides with DIN912, so there is no difference in the use of the new standard, mainly the difference between GB70-76 and DIN912: for M8 series hexagonal products, the diameter of the round head of GB70-76 is 12.5MM, It is smaller than 13.27MM of DIN912. For M10 series inner hexagon products, the round head diameter of GB70-76 is 15MM, which is smaller than 16.27 of DIN912. For M12 series inner hexagon, the round head diameter of GB70-76 is 18MM. It is smaller than the opposite side 18.27 of DIN912, and the round head diameter of the inner hexagon GB70-76 of M16 and M20 series is 0.33MM smaller than that of DIN912, which are 24MM and 30MM respectively. DIN912 is 24.33MM and 30.33MM respectively. In addition, the width of the inner hexagon between the old standard and the German standard is different due to different standards. The inner side of GB70-76 is smaller, and it should be paid attention to in business operations.
