Summary of information:We have more than ten years of production experience in the screw industry, the main products are: hexagon nuts, hand-ti...

Among them, the pneumatic riveting machine is more commonly used. The pneumatic riveting machine is also equipped with a clamp for assembling the rivet. The existing clamp usually uses two rotating clamps for fastening and assembly, but the rotation easily causes the two clamps to buckle. Misalignment, thus affecting the assembly of the rivet.

The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a fastener with a new structure with a nut, which cannot be tightened by conventional tools during use, and is suitable for special occasions requiring anti-theft.

The meaning of bolt performance grade is an international standard. Bolts of the same performance grade, regardless of the difference in material and origin, have the same performance, and only the performance grade can be selected in the design. Strength grade The so-called 8.8 and 10.9 grades refer to the shear stress grades of bolts of 0.88GPa and 1.09GPa 8.8 Nominal tensile strength 800N/MM2 Nominal yield strength 640N/MM2 General bolts use XY to indicate the strength, X *100=tensile strength of this bolt, X*100*(Y/10)=yield strength of this bolt (because according to the regulations: yield strength/tensile strength=Y/10, that is, 0.Y is the yield strength ratio ) If the grade is 4.8, the tensile strength of this bolt is: 400MPa; the yield strength is: 400*8/10=320MPa. Another: stainless steel bolts are usually marked as A4-70, A2-70, and the meaning is otherwise explained Measurement: There are two main units of length measurement in the world today, one is the metric system, and the measurement unit is meters (m) and centimeters (cm). ), millimeter (mm), etc., are used more in Europe, my country and Japan and other Southeast Asian regions, the other is the British system, and the unit of measurement is mainly inches (inch), which is used more in the United States, Britain and other European and American countries. 1. Metric measurement: (decimal system) 1m2 =100 cm2=10000 mm2, imperial measurement: (8 decimal system) 1 inch = 8 inches 1 inch = 25.4 mm 3/8¢¢×25.4 =9.523, 1/4 ¢¢ The following products are indicated by their number, such as: 4#, 5#, 6#, 7#, 8#, 10#, 12#

In the prior art, after the screw is screwed into the workpiece, rust inhibitor is dripped on the edge of the screw to prevent rust in the later stage, but this traditional dripping method of rust inhibitor often produces rust inhibitor during the dripping process. Difficult to penetrate, or the problem that the anti-rust oil cannot penetrate due to the tight contact between the screw thread and the thread groove. In terms of material saving, the traditional anti-rust of screws often causes a lot of waste of anti-rust agent, and cannot achieve a good anti-rust effect of screws.

Two combination screws are also called two combination screws. As the name suggests, it consists of a screw with a spring washer or only a flat washer. After the thread rolling, the two components are combined together. Two combination screws are available in iron and stainless steel. For iron, there are screw materials such as screw wire 1010, 1018, 10B21, etc. The general iron pier needs to be electroplated, and electroplating is divided into environmental protection and ordinary. For example, there are environmentally friendly color zinc, environmentally friendly blue zinc, white zinc, color zinc, white nickel and other electroplating. Stainless steel two combination screws. The material is stainless steel 304.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: Yuanbao butterfly screws and bolts, full threaded screws, PCB board fixing columns, non-chamfered hexagonal nuts and other products, we can provide you with suitable products for you.
