Flange nut
The size of the flange nut and the general hex nut is basically the same as the thread size. Compared with the hex nut, the biggest difference is that the flange nut is a one-piece washer and nut, and there is a non-slip tooth pattern underneath, which increases The nut is in contact with the surface area of the workpiece, which is stronger and more tensile than the combination of an ordinary nut and washer.
General common flange nut specifications are generally below M20, because most of the flange nuts are used on the pipe and flange plate, so the flange nuts have less specifications than the nuts because of the constraints of the workpiece. Some of the flange nuts over M20 are mostly flat flanges, which means that there are no tooth marks on the flange surface. Most of these nuts are used in some special equipment and special places. The general sales companies do not have stock.
Flange nut connection factor
When selecting a flange connection nut, factors such as piping operating pressure, operating temperature, media type, and gasket type must be considered. The type of gasket, as well as the operating pressure and operating temperature, directly impose requirements on the strength of the fastener material. For example, a flanged joint of a low-pressure, highly toxic medium pipe sealed with a wound gasket, despite the fact that the operating pressure and temperature of the pipe is not high, requires a higher specific pressure when the wound gasket is initially sealed. Fasteners are also required to withstand heavy loads. Therefore, high-strength alloy steels are required for fasteners.
Screws are the main fasteners in mechanical equipment, and the open Allen wrench is an important tool for processing, production, and maintenance in the machinery industry. The main function of the Allen wrench is to screw and disassemble the screw, which is a revolution of the traditional wrench tool.
Allen wrench
The Allen key has the following advantages:
1. The Allen wrench can work quickly, working three to four times faster than traditional wrenches and faster than a quick wrench.
2. An open Allen key can be applied to 2-6 types of screws, and a double-wrench is only applicable to 2 types of screws.
An open Allen key is equivalent to 2-3 wrenches, which is equivalent to an adjustable wrench but can work quickly without adjusting the opening.
3. The long service life is not bad, and the front quick wrench is easy to be damaged.
4. The Allen wrench has a simple manufacturing process and costs less than a wrench.
5. The Allen wrench is lightweight, easy to carry, and effortless.
