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.

Casters, also known as universal wheels, have a structure that allows for 360 degree horizontal rotation under dynamic or static loads. This type of wheel is usually used in conjunction with fixed casters, which do not have a rotating structure and cannot rotate horizontally but can only rotate vertically. There are various materials for casters, including PP casters, PVC casters, PU casters, cast iron casters, nylon casters, TPR casters, etc. According to their load-bearing capacity, they can also be divided into micro casters, light casters, medium casters, heavy casters, and ultra heavy casters.

A hinge is a mechanical device used to connect two solids and allow for relative rotation between them. It is usually composed of movable components or foldable materials. The main function of the hinge is to assist in the opening and closing of the cabinet, by connecting the rotating pair, so that the door or cover can swing on the fixed frame. According to different installation positions, hinges can be divided into door hinges and cabinet hinges. Door hinges are used to allow doors to rotate naturally and smoothly to open and close, while cabinet hinges have more functions and designs, such as rotating 360 degrees, adjusting the gap between doors up, down, and left and right.
