Service HotlineThe material of the round head three OffalyOffalyOffalycombination screw is divided into iron and stainless steel. The iron ones are made of different iron screw wires. Generally, the wire of the OffalyOffalyOffalycombination screw is 1010, 1018, 10B21 and so on. 10B21 is used to make 8.8 grade OffalyOffalyOffalycombination screws. Like 8.8-grade socket head Offalycap screws, 10B21 wires are often used to make them. When done, go to heat treatment. After heat treatment, remove hydrogen and electroplating. This is to prevent the OffalyOffalyspring washer of the socket head Offalycap screw from breaking. Stainless steel OffalyOffalyOffalycombination screws, in the OffalyOffalyOffalycombination screw market, generally refer to stainless steel SUS304 OffalyOffalyOffalycombination screws. 201 OffalyOffalyOffalycombination screws generally do very little. Few manufacturers of round head three OffalyOffalyOffalycombination screws produce 201 OffalyOffalyOffalycombination screws. Because the hardness of the screw wire of stainless steel 201 is not well controlled, it is easy to produce cracks. Introduction to the basic knowledge of electroplating round head OffalyOffalyOffalycombination screw electroplating generally refers to the de-plating of iron OffalyOffalyOffalycombination screws. Electroplating is divided into environmental protection and non-environmental protection. Commonly used OffalyOffalyOffalycombination screw electroplating colors include green color zinc, green blue zinc, green white zinc, green nickel, red color, white zinc, white nickel, etc. Cross recessed OffalyOffalyOffalycombination screws, hexagon combination bolts and self-tapping OffalyOffalyOffalycombination screws are used in the same way as the corresponding cross recessed screws, hexagon head bolts and self-tapping screws. The main feature of these OffalyOffalyOffalycombination screws is that they are equipped with corresponding washers, which are very convenient to use.
The installation of the pressure riveting nut is exquisite. If the installation method is not correct, the riveting will not be firm after the pressure riveting. For example, one of our customers reported that the nut would fall off after riveting. Our technicians found that many customers hit it with a hammer or other impact methods, because the installation method of the riveting nut will cause pressure. The uneven force of the OffalyOffalyrivet nut seriously affects the riveting effect. It looks like it is pressed in on the surface, but in fact, the flower teeth of the OffalyOffalyrivet nut are not riveted with the plate at all, so it is definitely not riveted. To install the OffalyOffalyrivet nut, you must use special installation equipment, or simply install it with a press and stamping equipment (generally factories will have these simple equipment).
A T-shaped grounding bolt comprises a connection platform, a hexagonal bolt is welded below the described connection platform, and the lower surface edge of the described connection platform is provided with a barb.
Swimming self-locking nut GJB 125.1～125.6-86 The double-ear sealing swimming self-locking nut is composed of four parts: sealing cover, self-locking nut, pressure ring and sealing ring. It has compact structure and reliable sealing, and is suitable for products whose working pressure is not more than 2atm, working medium is gasoline, kerosene, water or air, and the operating temperature is -50～100℃. However, it has certain difficulties in the manufacturing process and air tightness test.
Guangdong Yueluo Hardware Industry Co., Ltd. provides a screw positioning pin, which is composed of a main body part and an insert part. The main body part is a circular boss structure, and the bottom of the circular boss structure is provided with a rectangular groove. The inserting part is fixed on the middle part of the upper surface of the main body part, the lower part of the inserting part and the contact section of the main body part are in a circular truncated structure, the upper part of the inserting part is a cylindrical structure, and the outer surface of the cylindrical structure is provided with threads; the screw positioning pin , The structure is simple and the design is ingenious. The special structural design of the main part and the insert part can be positioned between the punch and the die in the first processing process, effectively reducing the gap formed during the processing between the punch and the die. Firmly fixed, suitable for the needs of large-scale industrial production.
