Detailed Photos & Description

Product Description

This is a black - colored hook bolt. It consists of a threaded shank and a hook - shaped end. The threaded part allows it to be screwed into a corresponding hole or nut, while the hook end can be used to catch or fasten onto other components.

Manufacturing Process

1. Raw Material Selection: Usually made from high - strength steel. The steel is first selected based on the required mechanical properties such as tensile strength and ductility.
2. Forming: The steel is shaped into the hook bolt form. This may involve processes like forging to create the hook shape and the shank, and then machining operations. Forging helps in aligning the metal grains, improving the strength of the bolt.
3. Heat Treatment: To enhance the strength and hardness, heat treatment processes such as quenching and tempering may be applied. Quenching rapidly cools the bolt to increase hardness, and tempering then reduces brittleness.
4. Surface Treatment: The black color suggests a surface treatment, likely black oxide coating. This coating not only provides a decorative appearance but also offers some corrosion resistance. The black oxide process involves converting the surface of the steel into a magnetite layer through chemical reactions.

Function

The hook bolt serves to fasten or secure objects in a specific way. The threaded shank can be anchored in a fixed structure (such as screwing into a threaded hole in a metal plate or a nut), and the hook end can hold onto another part, like hooking over a rim or a protrusion, providing a form of mechanical connection that can withstand certain tensile or shear forces depending on the application.

Application Scenarios

1. Industrial Machinery: In some industrial machines, it can be used to secure guards, panels, or auxiliary components. For example, in a large - scale printing press, it might be used to fasten a side panel that needs to be opened for maintenance occasionally. The hook can easily be unhooked and reattached.
2. Automotive Industry: It could be applied in automotive interiors or exteriors for securing parts that need periodic access. For instance, in some custom car builds, it might be used to fasten a removable roof panel or a special trim piece.
3. Furniture Manufacturing: Used to assemble or secure furniture components. For example, in the construction of a modular storage unit, the hook bolt can be used to connect different sections together, especially where a traditional bolt - nut connection might be less convenient, and the hook provides a quick - connect/disconnect feature.
