Introduction to countersunk hexagonal bolts
The countersunk hexagonal bolt is a special type of bolt with a countersunk head design, which allows the head to sink into the interior of the component, resulting in a smooth and non protruding surface after installation. The outer edge of the head of this bolt is round, and the middle is a concave hexagon, which requires the use of an Allen screwdriver for installation. The design of countersunk hexagonal bolts makes them particularly useful in mechanical connections that require aesthetics, high precision, and strict space requirements. In addition, there are various specifications and sizes of countersunk hexagonal bolts, including M2, M3, M4, M5, M6, M8, M10, M16, etc., to meet the needs of different application scenarios.
The advantages of countersunk hexagonal bolts include easy fastening, non disassembly, small space occupation, ability to withstand large loads, and the ability to be countersunk, allowing the bolt to sink into the interior of the workpiece, making it more delicate and aesthetically pleasing without obstructing other components. This makes countersunk hexagonal bolts particularly popular in mechanical connections that require aesthetics and high precision. However, they also have some drawbacks, such as small contact area, low preload force, and lack of full threads beyond a certain length, which may make them less suitable for certain applications than other types of bolts.
Overall, countersunk hexagonal bolts play an important role in mechanical connections that require aesthetics, high precision, and strict space requirements due to their unique design and advantages. Their application scenarios include the connection of small devices, mechanical connections that require high aesthetic and precision requirements, situations that require countersunking, and narrow assembly situations.
Countersunk hexagonal bolts are mainly used in situations where a flat and aesthetically pleasing surface needs to be maintained, especially in mechanical manufacturing and equipment installation.
The special design of the countersunk hexagonal bolt allows its head to sink into the interior of the workpiece, maintaining the flatness and aesthetics of the workpiece surface. The outer edge of the screw head of this bolt is round, and the middle is a concave hexagon, forming a 90 degree vertebral body. After installation, the screw head can be inserted into the installation surface, suitable for areas where there should be no protrusions on the surface of the parts after installation. The advantage of countersunk hexagonal bolts is that they are easy to tighten and disassemble, and are not prone to slipping, especially when used in narrow spaces. In addition, due to its head design, it can reduce the occupation of installation space and is suitable for occasions that require compact design.
The use of countersunk hexagonal bolts is extensive and commonly found in mechanical equipment, such as the hinges of chassis and the connection between doors and boxes. The design of this bolt takes into account force transmission and anti slip performance, allowing it to be used in confined spaces and providing higher torque transmission capabilities, reducing the risk of sliding and damage. In addition, due to its difficulty in disassembly, it is also commonly used in situations that require safe fixation and are not easily disassembled by non professionals.

Structure of electric vehicle follow-up brake: It mainly includes components such as brake box, two brake shoes, crank, reset spring, adjusting parts, tension column, etc. Specifically, the working principle of the follow-up brake is to increase the rotation angle of the two brake shoes during braking through the setting of metal plates and reels, thereby increasing the maximum braking resistance. This structure achieves the adjustment of braking effect through two brake shoe blocks hinged on the hinge shaft fixed on the brake box, as well as adjusting components provided on the brake box on one side of the hinge shaft. In addition, the follow-up brake also has a lock that can lock the brake disc components, providing dust-proof and waterproof functions to ensure brake sensitivity
