A gasket is a mechanical sealing element placed between two connecting surfaces. Its core function is to fill the microscopic unevenness of the joint surfaces, forming an effective seal to prevent leakage of the medium (liquid or gas) or intrusion of external impurities. Simultaneously, it can also distribute bolt loads, protect the connecting surfaces, and in some cases provide auxiliary functions such as insulation and anti-loosening.

Fully Threaded Structure: Fully threaded from one end to the other, providing a continuous meshing surface. This allows nuts or threaded components to be fixed and adjusted at any position within their length, offering exceptional flexibility.

Screws, like bolts but differ in use, often fit into pre-drilled holes or form threads in soft materials, serving for fastening, connecting, or positioning.

Nuts, as one of the most basic mechanical fasteners, are used in conjunction with bolts and screws to connect two or more parts together through the locking force of their threads. They come in a wide variety of types, selected according to the requirements of strength, anti-loosening properties, corrosion resistance, and assembly efficiency under different working conditions.

Machine screws typically consist of a head and a shank. Their most prominent feature is the fully threaded shank with a consistent thread diameter, not a tapered one. Designed to perfectly match pre-drilled internal threaded holes, this connection method is not only strong and reliable but also offers excellent repeatability. Due to their compact structure and high precision, they are widely used in various industrial and consumer products requiring strong and reliable connections.

Bolts, as one of the most basic and important mechanical fasteners, are hailed as the "rice of industry." Their existence allows for the stable connection of steel structures and precision instruments. Simply put, a bolt is a cylindrical fastener consisting of a head (which bears the tightening torque) and a shank (with external threads). It is usually used in conjunction with a nut with internal threads, or screwed directly into the threaded hole of the connected parts. The engagement of the threads generates a huge clamping force, firmly connecting two or more components together.

Hex bolt is the authoritative technical standard for hexagonal head fully(half) threaded bolts, established by the German Association for Standardization (DGBAS). A key characteristic of these bolts is that the shank has a complete, continuous thread from start to finish (commonly known as "full thread" or "through thread"). It is one of the most commonly used and classic mechanical fasteners, widely applied across various industries due to its simple design, reliable performance, and easy installation. Bolts conforming to DIN 933/931 are widely recognized and used globally, especially in Europe and regions heavily influenced by the German industrial system.

Anchor is a device embedded in a substrate (like concrete, masonry, or rock) to securely connect and fix components (e.g., steel structures, pipes, equipment) to the substrate. It transfers load from the object to the substrate's depths via mechanical interlocking, friction, or chemical bonding.
