What is the tolerance range of precision screws?
For achieving the above purpose, Guangdong Yueluo Hardware Industry Co., Ltd. provides the following technical solutions: a pin, comprising a pin cap and a described pin rod, the pin cap and one end of the pin rod are fixedly connected, and the pin rod There is a convex body, the convex body is fixedly connected with the pin rod, the convex body is located on the pin rod rod body, and the other end of the pin rod is provided with a top connecting body, and the top connecting body is fixedly connected with the pin rod , the top contact body includes several top contact units and discs, each top contact unit is coaxially arranged with the pin rod, the top contact units are sequentially fixedly connected along the axis direction of the pin, the top contact unit is The major diameter of the outer contour of the connecting body is larger than the diameter of the pin rod.
Guangdong Yueluo Hardware Industry Co., Ltd. has a simple structure, low processing difficulty, and convenient riveting. The whole pin has the same diameter except for the annular groove. The drawn wire can be directly used, which saves the cost of materials and machining costs, and improves the production speed and efficiency. The structure does not require high machining accuracy of the hole, which can effectively reduce the machining cost and the rework rate of the parts.
The safety of screws and bolts in important occasions is related to the safety of the overall operation of the equipment, especially in public places and open air places, the theft of screws will cause major safety hazards. It is easy to loosen, and there is a safety hazard in long-term use.
Alloy Steel Nuts Hexagon Nuts (GB6170/DIN934, GB6175), Flange Nuts (GB6177/DIN6923) Round Nuts (GB812), Small Round Nuts (GB810), American Square Nuts, American Hex Nuts (NI/MEB18.2.2), Heavy Duty Nuts (Metric, US). Specifications: 5/16-4. Nut specification editing Nut specification table is to unify all kinds of nuts in detail, and use the table to subdivide some specifications of nuts. There are many types of nuts, and there are nuts of different materials. 。 Each type of nut has different specifications, and each type of screw also has its own mechanical properties and functions.
