High strength hexagonal bolts are a type of metal accessory typically made of high-strength steel, with high tensile and compressive strength, suitable for applications that require high loads. The characteristics of this type of bolt include high strength, durability, and the ability to maintain fastening even in harsh environments such as heavy loads and vibrations. The application range of high-strength hexagonal bolts is wide, including but not limited to the connection of bridges, steel rails, high and ultra-high voltage equipment. In order to ensure the sealing of the container on ultra-high pressure equipment, high-strength hexagonal bolts need to be subjected to significant pre stress. In addition, the installation of high-strength external hexagon bolts usually adopts a method that does not require rework, and can be quickly connected even under insufficient conditions
High strength hexagonal bolts can be classified into various types based on their performance levels and application scenarios. For example, GB5783 high-strength 8.8 grade carbon steel hexagon bolt is a type of high-strength hexagon bolt in the national standard category, widely used in factories, mines, steel structure engineering and other occasions. Its performance level is 8.8 grade, the material is high-strength carbon steel, and it has good tensile strength and high-strength tensile performance.
Overall, high-strength external hexagonal bolts play an important role in various environments that require heavy loads and vibrations due to their high strength, durability, and quick installation characteristics. They are one of the indispensable fasteners in industrial manufacturing, construction engineering, and other fields.
Standard for high-strength hexagonal bolts
The standards for high-strength hexagonal bolts mainly include the national standards GB5783-86 and GB/T1228-2006. These standards specify the technical requirements for bolt size, material, strength grade, etc., ensuring the quality and performance of bolts.
Specific content of the standard
The specific contents of these standards include:
Thread diameter (d): The nominal diameter of the threaded portion of the bolt.
Bolt length (L): The length from the lower plane of the bolt head to the end of the bolt.
Pitch (P): The distance between threads (usually divided into coarse and fine threads).
Head to side width (S): The width of the opposite side of a hexagonal head.
Head height (K): The height of a hexagonal head.
Materials and strength grades: such as carbon steel, stainless steel, alloy steel, etc., and their strength grades (such as 4.8, 8.8, 10.9, 12.9, etc.).
Scope and Importance of Standard Application
These standards are widely used in the fields of architecture and engineering, especially in situations where high-strength connections are required. For example, in the structural connections of bridges and buildings, high-strength external hexagonal bolts can provide sufficient fastening force and tensile strength to ensure the safety and stability of the structure.

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.

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
